    Abstract: Imidyl compounds of the formula (I) wherein n is 1 or 2, R1 and R? each represent alkyl or together represent a tri- or tetramethylene group, Y represents, for example, alkylene, cycloalkylene and X represents various organic groups as detailed, are suitable for the manufacture of polymers which can be crosslinked by light. Suitable polymers include polyesters, polyamides, polyamide-imides, polyimides, polyester-polyamides, polyester-amido-imides, polyethers, polyamines, polysaccharides and polysiloxanes. Polymers of this type are suitable for carrying out photochemical processes. Compared with known polymers, the polymers based on the imidyl compounds according to the invention have the advantage that they are photochemically substantially more sensitive. In addition, this sensitivity can also be further increased effectively by a combination with sensitisers.

    Abstract: Substituted tetrathiotetracenes and tetraselenotetracenes of the formula I (I), in which Z is -S- or -Se- and a) R1, R2, R3 and R4 are H and R5 to R8 are each H and at least one of the radicals R5 to R8 independently of one another is a substituent belonging to the group comprising C1-C20alkyl?X? which is unsubstituted or substituted by halogen, -CN, -CONR9R10, -OR9, -SR9 or -COOR9, with the exception of C1-C4alkyl and methoxy, C2-C18alkenyl?X?, C2-C18-alkynyl?X?, C3-C8cycloalkyl?X?, (C1-C12alkyl)-C3-C8cyclo-alkyl?X?, C3-C8cycloalkyl-CrH2r?X?, (C1-C12alkyl)-C3-C8-cyclo alkyl-CrH2r?X?-, phenyl?X?, (C1-C12)alkyl)-phenyl?X?, phenyl-CrH2r?X? and (C1-C12alkyl)-phenyl-CrH2r?X?, r is 1 or 2 and p is 0 or 1 and X is -O-, -S-, -SO- or -SO2-, or R5 to R8 independently are a substituent belonging to the group comprising -Br, -CF3, -CN, -Si(C1-C4alkyl)3, -S-(CmH2m? or -O?CmH2m-?, or each one of R5 to R8 is -F or -Cl and at least one further member of R5 to R8 is a substituent of the groups defined above, including C1-C4alkyl and methoxy, R9 and R10 independently of one another are H, C1-C12alkyl, phenyl or ?CmH2m-O?, or R9 and R10 together are tetramethylene, pentamethylene, 3-oxapentylene or -CH2CH2NR9CH2CH2-, R11 is H or C1-C12-alkyl, m is a number from 2 to 4, n is a number from 2 to 20 and q is a number from 1 to 20, or b) R1 to R8 independently of one another are H or one of the substituents defined above, including C1-C4alkyl and methoxy, or -COOR9 or -CONR9R10 or two pairs of adjacent radicals of R1 to R8 are -CO-O-CO- or -CO-NR9-CO-, and at least one of R1 to R4 and also R5 to R8 is a substituent, with the exception of R2, R3, R6 and R7 when these are -F and methyl, and where R9 and R10 are as defined above. With electron acceptors they form charge-transfer complexes which can be used as organic electrical conductors, displays, optical switches and sensors.
