Description

  The present invention relates to a method for producing an organic thin film, and particularly relates to a method for producing an organic thin film including a step of washing a substrate with an alkaline aqueous solution.

  Various methods are known as a method of forming an organic thin film on the surface of a substrate such as a substrate. For example, Patent Document 1 discloses that in a method for producing a chemical adsorption film on the surface of a substrate containing active hydrogen, a metal surfactant having at least one hydrolyzable group is added to a metal oxide in an organic solvent. Alternatively, there is disclosed a method for producing a chemisorbed film comprising a step of bringing a metal alkoxide partial hydrolysis product and a solution treated with water into contact with the substrate surface. Patent Document 2 discloses an organic thin film manufacturing method including a step of bringing an organic solvent solution containing a metal compound having a hydrocarbon group, a hydrolyzable group or a hydroxyl group on a metal atom, a metal catalyst, and water into contact with a substrate. The concentration of the metal compound in the solution is in the range of 5 to 15 mmol / kg, the metal catalyst is in the range of 1 to 20 mol% with respect to the metal compound in terms of oxide, and the concentration of water in the solution Is disclosed in a method for producing an organic thin film characterized in that the content is in the range of 50 to 500 ppm.

  When manufacturing these organic thin films, before the organic thin film is formed on the surface of the base material, it is generally used for the purpose of decomposing organic substances on the surface of the base material or forming an oxide film on the surface of the base material. It is known that UV / ozone cleaning is performed. Patent Document 3 discloses a method for producing an organic thin film using ozone water or hydrogen peroxide water for cleaning a substrate. It is also well known to treat a substrate with an alkaline cleaning solution.

  However, in the production of an organic thin film that forms an organic thin film on the surface of the base material, a specially expensive device is required when performing the UV / ozone cleaning process, and the worker himself installs the base material on the device. However, it is necessary to take out the base material from the apparatus after the treatment, which is a process that cannot be automated in the manufacturing process of the organic thin film. Furthermore, it was difficult to clean a complicated three-dimensional structure. When ozone water or hydrogen peroxide water is used as a cleaning agent, the effective period of the cleaning agent is short, and in particular, ozone water must be used immediately after adjustment, which is inconvenient. Further, the alkaline cleaning liquid causes corrosion on a metal substrate such as copper, and some metal substrates are not suitable for cleaning.

Thereby, impurities such as dust, dust and organic matter on the surface of the substrate can be removed to a higher degree, and the organic thin film can be formed more densely and firmly. When both the step (C) and the step (D) are included, the order of the step (C) and the step (D) is not limited, but the step (D) is preferably included after the step (C). Moreover, when it has a process (C) and / or a process (D) after a process (A), you may have a process (C) and / or a process (D) after the below-mentioned process (E). However, it is preferable to have before process (E).

  Here, the distilled water in step (C) is not particularly limited, but from the viewpoint of obtaining a more excellent cleaning effect, distilled water having a resistance value of 10 mega ohms or more is preferable, and distillation having a resistance value of 15 mega ohms or more. More preferably, it is water.

  Moreover, the organic solvent in the step (D) is not particularly limited, but alcohols such as ethanol and isopropanol are preferable, and ethanol and isopropanol are particularly preferable.

  In addition, the washing method in the step (C) or (D) is not particularly limited, and for example, the base material is sprayed or showered with the distilled water in the step (C) or the organic solvent in the step (D). Alternatively, the substrate may be immersed in the distilled water of step (C) or the organic solvent of step (D). Since a more excellent cleaning effect can be obtained, it is preferable to perform ultrasonic treatment in a state where the substrate is immersed in distilled water in the step (C) or an organic solvent in the step (D). As specific conditions for the ultrasonic treatment, the same conditions as in the case of ultrasonic treatment by immersing the base material in ozone water or hydrogen peroxide solution can be exemplified. In addition, if a physical method of exposure to ultraviolet rays, ozone, or plasma is further used, a further excellent cleaning effect can be obtained.

  The manufacturing method of the organic thin film of this invention may include the process (E) which wash | cleans a base material with an organic solvent after a process (B). If there exists such a washing | cleaning process (E), the excess reagent and impurity adhering to the surface of the organic thin film formed at the process (B) will be removed. Moreover, the film thickness of the organic thin film formed in the base-material surface can be controlled by providing such a washing | cleaning process (E).

The organic solvent in the step (E) is not particularly limited, but hydrocarbon solvents such as hexane, heptane, octane, nonane, decane, benzene, toluene, xylene and the like are preferable.
The cleaning method is not particularly limited as long as it can remove deposits on the surface of the substrate. For example, a method of immersing the substrate in an organic solvent as described above; in a vacuum or in the atmosphere under normal pressure Examples thereof include a method of allowing the deposit on the surface of the substrate to evaporate; a method of blowing an inert gas such as dry nitrogen gas to blow away the deposit on the surface of the substrate; and the like. Moreover, since the more outstanding cleaning effect is acquired, it is mentioned as a more preferable method to carry out ultrasonic treatment in the state which immersed the base material in the above-mentioned organic solvent.

  The method for producing an organic thin film of the present invention preferably further includes a step (F) of drying the substrate washed in the step (E) after the step (E). The drying method is not particularly limited, and the solution on the surface of the substrate may be an air knife or the like, may be naturally dried, and can be exemplified by a method such as applying hot air. A method of applying warm air is preferable because the organic thin film is further stabilized by applying heat to the formed organic thin film.

  In addition, when heat is not applied to the base material when drying the base material, the organic thin film production method of the present invention may not further include a step of applying heat to the base material. In order to stabilize, it is preferable to further include the step (G) of applying heat to the substrate. The order of the step (G) is not particularly limited as long as it is after the step (B), (B-1), (B-2) or (B-3), but may be after the step (E). preferable. Although the temperature to heat can be suitably selected according to stability of a base material and an organic thin film, the range of 40-70 degreeC can be mentioned preferably, for example.

  The method for producing an organic thin film of the present invention is not particularly limited as long as it includes the step (A), and before and / or after any one or more of the steps in addition to the steps (A) to (F). Any process may be included.

  The base material used for the manufacturing method of the organic thin film of this invention is not restrict | limited in particular. The substrate used in the method for producing an organic thin film of the present invention may not be a substrate having a functional group on the surface capable of interacting with molecules forming the organic thin film in the organic solvent solution, but in the organic solvent solution. A substrate having a functional group capable of interacting with molecules forming the organic thin film on the surface is preferable, and a substrate having active hydrogen on the surface is particularly preferable. When a substrate having active hydrogen on the surface is used, the active hydrogen on the substrate surface and the molecules in the organic solvent solution in the step (B) can be easily chemically adsorbed on the substrate surface by chemical interaction. Can be formed. Here, the base material having a functional group capable of interacting with a molecule forming an organic thin film in an organic solvent solution on the surface means a functional group capable of chemically bonding with the molecule forming the organic thin film in the organic solvent solution. It means a substrate having on the surface.

Here, active hydrogen refers to those that are easily dissociated as protons, and functional groups containing active hydrogen include hydroxyl groups (—OH), carboxyl groups (—COOH), formyl groups (—CHO), and imino groups (═NH). ), An amino group (—NH ₂ ), a thiol group (—SH), etc., among which a hydroxyl group is preferable.

  Specifically, as a base material having a hydroxyl group on the surface of the base material, metals such as aluminum, copper, stainless steel and nickel; glass; silicon wafers; ceramics; plastics; minerals such as diamond; paper; Examples of the base material include fibers, leather, other hydrophilic substances, and the like. Especially, the base material which consists of a metal, glass, a silicon wafer, ceramics, paper, a fiber, a plastics, and a mineral is preferable.

  For a substrate made of a material that does not have a hydroxyl group on its surface such as plastic, diamond, or synthetic fiber, the substrate surface is previously treated in an oxygen-containing plasma atmosphere (for example, 100 W for 20 minutes) or corona treated. A hydrophilic group can be introduced. A substrate made of a polyamide resin or a polyurethane resin has an imino group on the surface, and the active hydrogen of the imino group and the alkoxysilyl group of the metal-based surfactant undergo a dealcoholization reaction to form a siloxane bond (- Since SiO-) is formed, no surface treatment is required.

In the case of using a substrate that has no active hydrogen on the surface, the surface of the substrate, previously _{SiCl 4, SiHCl 3, SiH 2} Cl 2, Cl- (SiCl 2 O) b -SiCl 3 ( wherein, b It is also possible to form a silica underlayer having active hydrogen on the surface thereof by contacting with at least one compound selected from (natural number) and then dehydrochlorinating.

  The method for preparing the organic solvent solution in the step (B-1) of the present invention is not particularly limited. The organic solvent solution in the step (B-1) of the present invention includes, for example, a metal surfactant having at least one hydrolyzable group, a compound that can interact with the metal surfactant, and an organic solvent. It can be prepared, for example, by stirring the mixture.

  Although stirring temperature is not specifically limited, For example, -100 degreeC-+100 degreeC may be sufficient, and it is preferable that it is -20 degreeC-+50 degreeC. Further, the stirring time is not particularly limited, but it can be performed for several minutes to several hours.

  In the prepared organic solvent solution, precipitates containing metal oxides and the like may be generated. In order to obtain a dense monomolecular organic thin film with less impurities, the impurities such as these precipitates are the basis. It is preferable to remove or reduce these impurities before contacting the material. Precipitates can be easily removed or reduced by operations such as filtration and decanting.

The organic solvent solution in the step (B-1) of the present invention may not be an organic solvent solution adjusted to or retained in a predetermined moisture content, Since a denser and more uniform organic thin film can be formed more quickly, it is preferable that the organic solvent solution be adjusted and held so as to have a moisture content within a predetermined range.
When the water content of the organic solvent solution is adjusted within a predetermined range, a denser monomolecular film is produced, the film formation is promoted and activated, and the amount of loss of the metal-based surfactant is reduced. Further, when the water content of the organic solvent solution is maintained within a predetermined range, for example, the step of continuously contacting two or more base materials with the organic solvent solution using the same organic solvent solution Even if it is performed, a denser and more homogeneous organic thin film can be formed more quickly in correspondence with substrates of any material. Here, the same organic solvent solution means that after performing the step (B-2) on one base material, the entire organic solvent solution used in the step is discarded and replaced with a new organic solvent solution. This means that a part of the organic solvent solution used in the process is discarded and a new organic solvent solution is added. In addition, the solution by which the moisture content was hold | maintained in the predetermined range with the some methods which are mentioned later is contained in the same organic solvent solution here.

  The “moisture content within a predetermined range” can be determined according to the type of substrate used, metal surfactant, compound capable of interacting with the metal surfactant, organic solvent, and the like. Specifically, as the “water content within a predetermined range”, for example, chemisorption on the substrate surface occurs more actively, a denser monomolecular film is produced, and the formation of the film is accelerated and activated. The amount of water content is more than the amount that can be used, or the amount of loss of the metal surfactant used is less, and the amount of water content is more than the amount that the compound capable of interacting with the metal surfactant can exhibit more sufficient activity. Is preferred.

For example, when the solution is brought into contact with the substrate by a dip method, the amount that promotes the formation of the film is dense and homogeneous in one contact (dip) within 10 minutes, preferably within 5 minutes. An amount that can form an organic thin film on the entire surface of the substrate. Specifically, the water content in the organic solvent solution in the step (B-2) is preferably 30 ppm or more, and the range of the saturated water content from 30 ppm to the organic solvent, more specifically, 30 to 1000 ppm. Is more preferable, and it is still more preferable that it exists in the range of 50-800 ppm. When the water content is 30 ppm or more, the organic thin film can be formed more rapidly, and when the water content is 1000 ppm or less, the metal surfactant and the like can exhibit more sufficient activity. .
The moisture content shown here is a value obtained by collecting a part of the organic solvent solution and measured by the Karl Fischer method, and the measurement device is particularly limited as long as it is a value measured by a device using the method principle. Not. When the organic solvent solution is uniform, a part of the uniform solution is sampled and measured. When the organic solvent layer and the moisture layer are two layers, a part of the organic solvent solution is sampled from the organic solvent layer. In the case where the water layer is dispersed in the organic solvent and cannot be separated, the measured value is obtained by collecting the dispersion as it is.

The method for preparing the organic solvent solution to a moisture content within a predetermined range is not particularly limited,
(1) A method of adding water to an organic solvent solution containing a metal surfactant and a compound capable of interacting with the metal surfactant,
(2) A method of adding a compound capable of interacting with a metal surfactant to an organic solvent solution containing a metal surfactant and water can be exemplified.

These methods may be used alone or in combination of two or more.

  The water used for adjusting or maintaining the water content is not particularly limited as long as it is neutral, but is preferably pure water or distilled water. Further, the organic solvent used in the organic solvent solution in the step (B-1) may be anhydrous or may contain a certain amount of moisture in advance.

  In the method of providing an aqueous layer in contact with the organic solvent solution of (1) above, when an organic solvent that separates from the aqueous layer, such as a hydrocarbon solvent, is used, the aqueous layer is separated from the organic solvent layer. The organic solvent layer separated from the water tank after circulating or passing the organic solvent solution through the aqueous layer may be used. When an organic solvent that has high water solubility and does not separate from the aqueous layer, such as a lower alcohol, is used, the organic solvent solution and the aqueous layer are brought into contact with each other through a membrane that does not penetrate the organic solvent but penetrates the water. A method etc. can be illustrated.

The water-retaining substance in the method of providing the water-retaining substance (2) containing water in contact with the organic solvent solution is not particularly limited, but water is not separated in the organic solvent solution, and the organic solvent It is preferable that the substance does not float in the solution. Specifically, organic water retention materials such as water-absorbing polymers; inorganic water retention materials such as zeolite, silicate clay, vermiculite, and porous ceramics; surfactants and the like micellar molecules having water as a nucleus in the solution. A glass fiber filter is particularly preferable because it can avoid contamination of dust and the like.
Moreover, when the water retaining substance containing water is provided in contact with the organic solvent solution, it is preferable that the water retaining substance coexists in the solution in a state containing moisture.
Furthermore, in order to increase the solubility of water in the organic solvent, a method using a hydrophilic solvent is also conceivable. The hydrophilic solvent in this case is also included for convenience in the water-retaining substance in the present invention.

  The amount of water contained in the water-retaining substance is not particularly limited, but is preferably a water amount within a range where water is not separated from the water-retaining substance in the organic solvent solution. In addition, moisture can be replenished to the water-retaining substance by adding water to the water-retaining substance at an appropriate time. Further, by continuously providing the water-retaining substance from the interface between the solution and the outside air or from the outside air to the inside of the solution, it is possible to absorb moisture of the outside air and supply water to the organic solvent solution.

Moreover, in the method of contacting the organic solvent solution of (3) above with a gas containing moisture, the gas used is not particularly limited as long as it does not affect each component in the solution. Specifically, Examples thereof include air, nitrogen gas, and argon gas. A method for obtaining a gas containing moisture is not particularly limited, and examples thereof include a method of adding moisture to the gas; a method of humidifying the gas;
The method of adding moisture to the gas is not particularly limited, but is a method of bringing the gas into contact with water such as submerging the gas in water or bringing the gas into contact with the water or hot water surface; a method using the gas containing water vapor as it is; Can be illustrated.
The method for humidifying the gas is not particularly limited, and examples thereof include a steam humidification method, a water spray humidification method, and a vaporization heating method.

  The method of bringing the moisture-containing gas into contact with the organic solvent solution is not particularly limited, but a method in which a moisture-containing gas is blown into the organic solvent solution or sprayed onto the surface of the organic solvent solution; Examples include a method in which the organic solvent solution is allowed to stand under stirring in an atmosphere, and a method in which the organic solvent solution is allowed to stand in a humidified atmosphere with stirring as necessary. In the method of blowing a gas containing moisture, it is preferable to attach a blowing device, a cleaning device, a filtering device, or the like as necessary.

  Further, the method of adding water appropriately as described in (4) above is not particularly limited. For example, a decrease in the amount of water in the organic solvent solution is observed, and water, a compatible organic solvent or the same solvent is used according to the amount of decrease. Examples include a method of appropriately adding water diluted with an organic solvent of (2) to an organic solvent solution; a method of supplying an organic solvent solution having the same composition containing a certain amount of water; and the like.

Specifically, as a method of immersing the substrate while maintaining the amount of water in the organic solvent solution,
(A) A method of providing a moisture adjustment tank and a substrate immersion tank, and circulating an organic solvent solution adjusted in moisture in the moisture adjustment tank to the substrate immersion tank;
(B) A method of adjusting the water content of the organic solvent solution in another immersion tank while providing a plurality of substrate immersion tanks and immersing the substrate in one substrate immersion tank,
(C) As described above, there is a method in which means for maintaining the water content within a predetermined range is directly provided in the base material immersion tank, and water is appropriately replenished.

  The step (B-1) of bringing the substrate into contact with the organic solvent solution may not be performed in a space where the humidity is maintained at 40% RH or higher, but in a space where the humidity is maintained at 40% RH or higher. It is preferable to carry out in the above, and it is more preferred to carry out in a space where the humidity is maintained at 60% RH or higher. In such a space, the amount of water in the organic solvent solution is more preferably maintained, and even if the substrate is continuously contacted with the organic solvent solution, a denser monomolecular film is formed with better reproducibility. be able to.

  The method for producing an organic thin film of the present invention can be used for production of a monomolecular film as well as for production of a multilayer film having two or more layers, but can be particularly suitably used for production of a monomolecular film. Moreover, it can be used not only as a method of forming an organic thin film on the surface of the substrate by chemical adsorption, but also as a method of forming an organic thin film on the surface of the substrate by physical adsorption.

  In the method for storing an organic solvent solution of the present invention, an organic solvent solution containing a metal surfactant having at least one hydrolyzable group and a compound capable of interacting with the metal surfactant is treated with water. Thus, the water content in the organic solvent solution is set within a predetermined range, and the water content in the organic solvent solution is kept in the predetermined range, and the method of sealing in the container can be exemplified. . Examples of the method for keeping the water content in the organic solvent solution within a predetermined range and maintaining the water content in the organic solvent solution within the predetermined range include the same methods as described above.

  By sealing the organic solvent solution of the present invention in a container, it is possible to prevent moisture from being volatilized into the atmosphere together with the organic solvent and reducing the amount of water. Since the water content of the organic solvent solution of the present invention affects the ability to form an organic thin film, it is preferable to keep the water content in the organic solvent solution within a predetermined range even during storage.

  By using the method for producing an organic thin film of the present invention, a monomolecular film, a self-assembled film, a chemical adsorption film, and an organic thin film having these properties can be obtained.

  The monomolecular film in the present invention may not be a chemisorbed film or a self-assembled film, but is preferably a chemisorbed film and / or a self-assembled film. In the present invention, the self-assembled film means a film formed with an ordered structure without external forcing. In the organic solvent solution of the step (B-1), when molecules forming an organic thin film such as a metal surfactant having at least one hydrolyzable group form an aggregate, An organic thin film obtained using an organic solvent solution is a self-assembled film. The molecules of the metal-based surfactant in the step (B-1) are not solvated by the solvent in the organic solvent solution but exist alone, but some gather to form an aggregate. The aggregate can be obtained by treating the metal surfactant with a compound capable of interacting with the metal surfactant and water.

  The form of the aggregate is a form in which molecules are assembled by intermolecular forces, coordination bonds, hydrogen bonds, etc. between hydrophobic parts or hydrophilic parts; the molecules forming the membrane are bound by covalent bonds Aggregated form; Form in which other medium such as water forms micelles or the like as a nucleus or mediator; or a form in which these are combined;

  The shape of the aggregate is not particularly limited, and may be any shape such as a spherical shape, a chain shape, or a belt shape. The average particle size of the aggregate is not particularly limited, but is preferably in the range of 10 to 1000 nm.

  The chemisorption film according to the present invention is a chemisorption film formed on a base material, wherein the base material does not have crystallinity, and the chemisorption film has crystallinity. That is, the chemical adsorption film in the present invention has crystallinity regardless of whether the substrate is crystalline or not. In this case, the crystallinity may be polycrystalline or single crystal.

  When the substrate of the present invention is brought into contact with an organic solvent solution, the metal surfactant in the organic solvent solution is adsorbed on the substrate surface, and a thin film is formed. The details of the mechanism by which the metal surfactant is adsorbed on the surface of the substrate are not clear, but in the case of a substrate having active hydrogen on the surface, it can be considered as follows. That is, in the solution for forming an organic thin film, the hydrolyzable group of the metal surfactant is hydrolyzed with water. Then, the metal surfactant in this state reacts with active hydrogen on the surface of the base material to form a thin film that forms a strong chemical bond with the base material. This thin film is formed by reacting with the active hydrogen of the base material and becomes a monomolecular film.
