Abstract

Compounds of the general formula I <IMAGE> in which Y is a nitrogen or phosphorus atom, A<1> and A<2> are identical or different and are each a straight-chain or branched alkylene group having 2 to 6 carbon atoms, U<1>, U<2>, U<3>, U<4> are identical or different and are each a direct bond or a straight-chain or branched alkylene group having 1 to 6 carbon atoms, D<1>, D<2>, D<3>, D<4> are identical or different and are each an oxygen or sulphur atom, an alkylene group having 1 to 6 carbon atoms or a group N-R<7> where R<7> has the meaning of a hydrogen atom, a straight-chain or branched alkylene chain having 1 to 4 carbon atoms, which carries a COOR<1> group at the end, in which R<1> represents a hydrogen atom or a metal ion equivalent, D<5> has the meaning given for D<1>, D<2>, D<3> and D<4> and the group <IMAGE> where R<5> has the meaning of a hydrogen atom or of a straight-chain or branched, saturated or unsaturated C1-C20-alkylene group which may contain imino, phenyleneoxy, phenyleneimino, amide, ester groups, oxygen, sulphur and/or nitrogen atoms and may be substituted by hydroxyl, mercapto, imino and/or amino groups and has either a functional group or bound via this group a macromolecule B at the end, s and t are integers from 0 to 5, R<2> is hydrogen, a linear or branched, saturated or unsaturated, alkyl, acyl or acylalkyl group of 1 to 16 carbon atoms which is unsubstituted or substitute by one or more hydroxyl or lower alkoxy groups, or is -CH2-X-V where X has the meaning of carbonyl, of a straight-chain or branched alkylene group having 0 to 10 carbon atoms, which is unsubstituted or substituted by one or more hydroxyl or lower alkoxy groups, or of a straight &tilde& chain or branched alkylene group having 2 to 23 carbon atoms which is interrupted by oxygen atoms, V has the meaning <IMAGE> or -COOR<6> in which R<3> and R<4>, independently of one another, are hydrogen, a linear o branched alkyl group having 1 to 16 carbon atoms which is unsubstituted or substituted by one or more hydroxyl or lower alkoxy groups, or R<3> and R<4> together with the nitrogen atom represent a saturated 5- or 6-membered ring which may contain a further hetero atom and R<6> represents hydrogen or a saturated, unsaturated, straight-chain or branched or cyclic hydrocarbon radical having up to 16 carbon atoms or represents an aryl or aralkyl group, or R<2> or R<3> denotes a second macrocycle of the formula I' <IMAGE> which is bound via an alkylene chain (K) containing 2 to 20 carbon atoms, which, if desired carries carbonyl groups at the ends and, if desired, is interrupted by one or more oxygen atoms or R<1>-carboxymethylimino groups or substituted by one or more hydroxyl, lower alkoxy or carboxy-lower alkyl groups, which macrocycle can have a structure which is different from that of the parent structure, or R<2> denotes B or CH2-COB, with the proviso that if Rz represents B or CH2-COB, R<5> denotes a hydrogen atom, that at least two COORi groups are present in the molecule and that two hetero atoms of the macrocycle are each bound to at least two carbon atoms via an alkylene group and functional groups present in the molecule are, if desired conjugated with macromolecules and, if desired free carboxyl groups have been converted with organic or inorganic bases or amino acids and basic groups with inorganic or organic acids to the salts.
