Definitions
- the present invention relates to a compound for an organic thin film transistor and an organic thin film transistor using the compound for an organic semiconductor layer.
- Thin film transistors are widely used as display switching elements for liquid crystal display devices and the like.
- a typical TFT has a gate electrode, an insulator layer, and a semiconductor layer in this order on a substrate, and has a source electrode and a drain electrode formed on the semiconductor layer at a predetermined interval.
- the organic semiconductor layer forms a channel region, and an on / off operation is performed by controlling a current flowing between the source electrode and the drain electrode with a voltage applied to the gate electrode.
- the on / off ratio here refers to the current flowing between the source and drain when the gate voltage is applied (on) divided by the current flowing between the source and drain when the gate voltage is not applied (off).
- the on-current is a current value (saturation current) when the current flowing between the source and the drain is normally saturated while increasing the gate voltage.
- Patent Literature 1 discloses a compound having an arylethynylene group in order to obtain a TFT having a large field effect mobility and a high response speed.
- high mobility is obtained by performing monomolecular film processing on a substrate in manufacturing an element, and further performing evaporation while heating the substrate.
- monomolecular film processing on a substrate in manufacturing an element, and further performing evaporation while heating the substrate.
- evaporation while heating the substrate.
- Patent Documents 1 and 2 A typical material for organic TFTs is pentacene.
- Patent Documents 1 and 2 an organic TFT using pentacene as an organic semiconductor layer is manufactured. Since pentacene has a drawback of low stability in the atmosphere, the mobility decreased immediately with the passage of time, although it showed very high mobility immediately after the device was fabricated.
- Non-Patent Document 1 reports an organic TFT using picene, which is a condensed aromatic ring. It is described that picene is superior in oxidation stability of the compound in the atmosphere because it has a lower ionization potential than pentacene.
- picene when picene is used, although the mobility is 1.0 cm 2 / Vs, there is a disadvantage that a high driving voltage of the element of ⁇ 67 V is required.
- An object of the present invention is to provide an organic thin film transistor having high mobility and low driving voltage or applicable to a coating process, and a compound for organic thin film transistor used for producing the organic thin film transistor. .
- this invention is a compound for organic thin-film transistors represented by following formula (1).
- At least one pair of adjacent groups out of R 1 , R 3 , R 5 , and R 7 is bonded to each other, and is condensed or fused to a ring to which these groups are bonded.

本発明の有機薄膜トランジスタの素子構成は、少なくとも基板上にゲート電極、ソース電極及びドレイン電極の3端子、絶縁体層並びに有機半導体層が設けられ、ソース-ドレイン間電流をゲート電極に電圧を印加することによって制御する薄膜トランジスタである。そして、有機半導体層が上述した本発明の有機薄膜トランジスタ用化合物を含むことを特徴とする。
トランジスタの構造は、特に限定されず、有機半導体層の成分以外が公知の素子構成を有するものであってもよい。有機薄膜トランジスタの素子構成の具体例を図を用いて説明する。
図1の有機薄膜トランジスタ1は、基板10上に、相互に所定の間隔をあけて対向するように形成されたソース電極11及びドレイン電極12を有する。そして、ソース電極11、ドレイン電極12及びそれらの間の間隙を覆うように有機半導体層13が形成され、さらに、絶縁体層14が積層されている。絶縁体層14の上部であって、かつソース電極11及びドレイン電極12の間の間隙上にゲート電極15が形成されている。
以下、有機薄膜トランジスタの構成部材について説明する。
本発明の有機薄膜トランジスタにおける有機半導体層は、上述した本発明の有機薄膜トランジスタ用化合物を含む。有機半導体層の膜厚は、特に制限されることはないが、通常、0.5nm~1μmであり、2nm~250nmであると好ましい。
また、有機半導体層の形成方法は特に限定されることはなく公知の方法を適用でき、例えば、分子線蒸着法(MBE法)、真空蒸着法、化学蒸着、材料を溶媒に溶かした溶液のディッピング法、スピンコーティング法、キャスティング法、バーコート法、ロールコート法、インクジェット法等の印刷、塗布法及びベーキング、エレクトロポリマラインゼーション、分子ビーム蒸着、溶液からのセルフ・アセンブリ、及びこれらの組合せた手段により、前記したような有機半導体層の材料で形成される。
本発明において、有機半導体層には、式(1)で示される化合物の1種類を用いてもよく、複数を組み合わせたり、ペンタセンやチオフェンオリゴマー等の公知の半導体を用いて複数の混合薄膜又は積層して用いてもよい。
本発明の有機薄膜トランジスタにおける基板は、有機薄膜トランジスタの構造を支持する役目を担うものであり、材料としてはガラスの他、金属酸化物や窒化物等の無機化合物、プラスチックフィルム(PET,PES,PC)や金属基板又はこれら複合体や積層体等も用いることが可能である。また、基板以外の構成要素により有機薄膜トランジスタの構造を十分に支持し得る場合には、基板を使用しないことも可能である。また、基板の材料としてはシリコン(Si)ウエハが用いられることが多い。この場合、Si自体をゲート電極兼基板として用いることができる。また、Siの表面を酸化し、SiO2を形成して絶縁層として活用することも可能である。この場合、基板兼ゲート電極のSi基板にリード線接続用の電極として、Au等の金属層を成膜することもある。
本発明の有機薄膜トランジスタにおける、ゲート電極、ソース電極及びドレイン電極の材料としては、導電性材料であれば特に限定されず、白金、金、銀、ニッケル、クロム、銅、鉄、錫、アンチモン鉛、タンタル、インジウム、パラジウム、テルル、レニウム、イリジウム、アルミニウム、ルテニウム、ゲルマニウム、モリブデン、タングステン、酸化スズ・アンチモン、酸化インジウム・スズ(ITO)、フッ素ドープ酸化亜鉛、亜鉛、炭素、グラファイト、グラッシーカーボン、銀ペースト及びカーボンペースト、リチウム、ベリリウム、ナトリウム、マグネシウム、カリウム、カルシウム、スカンジウム、チタン、マンガン、ジルコニウム、ガリウム、ニオブ、ナトリウム、ナトリウム-カリウム合金、マグネシウム、リチウム、アルミニウム、マグネシウム/銅混合物、マグネシウム/銀混合物、マグネシウム/アルミニウム混合物、マグネシウム/インジウム混合物、アルミニウム/酸化アルミニウム混合物、リチウム/アルミニウム混合物等が用いられる。
低仕事関数金属の具体例としては、例えば化学便覧 基礎編II-493頁(改訂3版 日本化学会編 丸善株式会社発行1983年)に記載されている4.3eV又はそれ以下の仕事関数をもつ有効金属の前記リストから選別すればよく、Ag(4.26eV),Al(4.06,4.28eV),Ba(2.52eV),Ca(2.9eV),Ce(2.9eV),Cs(1.95eV),Er(2.97eV),Eu(2.5eV),Gd(3.1eV),Hf(3.9eV),In(4.09eV),K(2.28),La(3.5eV),Li(2.93eV),Mg(3.66eV),Na(2.36eV),Nd(3.2eV),Rb(4.25eV),Sc(3.5eV),Sm(2.7eV),Ta(4.0,4.15eV),Y(3.1eV),Yb(2.6eV),Zn(3.63eV)等が挙げられる。これらの中でも、Ba,Ca,Cs,Er,Eu,Gd,Hf,K,La,Li,Mg,Na,Nd,Rb,Y,Yb,Znが好ましい。電極材料としてはこれらの低仕事関数の物質を1種又は複数含んでいても、仕事関数が前記式(II)を満たせば特に制限を受けるものではない。ただし、低仕事関数金属は、大気中の水分や酸素に触れると容易に劣化してしまうので、必要に応じてAgやAuのような空気中で安定な金属で被覆することが望ましい。被覆に必要な膜厚は10nm以上必要であり、膜厚が熱くなるほど酸素や水から保護することができるが、実用上、生産性を上げる等の理由から1um以下にすることが望ましい。
本発明の有機薄膜トランジスタにおける絶縁体層の材料としては、電気絶縁性を有し薄膜として形成できるものであるのなら特に限定されず、金属酸化物(珪素の酸化物を含む)、金属窒化物(珪素の窒化物を含む)、高分子、有機低分子等室温での電気抵抗率が10Ωcm以上の材料を用いることができ、特に、比誘電率の高い無機酸化物皮膜が好ましい。
また、窒化ケイ素(Si3N4、SixNy(x、y>0))、窒化アルミニウム等の無機窒化物も好適に用いることができる。

有機半導体層の材料として、化合物(37)の代わりに比較化合物(1)を用い、溶解度を確認した。クロロホルムを用いて、0.5wt%溶液が得られなかった。そのため、懸濁液を用いて実施例13と同様にして有機薄膜トランジスタを作製したところ、作製した素子は有機薄膜トランジスタとしての特性を示さなかった。
