Abstract:
The invention relates to 9-cyano-substituted perylene-3,4-dicarboxylic acid monoimides (I) where the variables have the following meanings: X = a chemical bond, optionally substituted C1-C30 alkylenes, C5-C8 cycloalkylenes, arylenes, heteroarylenes, C1-C20 alkylarylenes, C1-C20 alkylheteroarylenes, aryl- or heteroaryl-C1-C20 alkylenes, Y = a functional group Y', or a polymerisable group P, or X-Y together = a group R, Y' = amino, hydroxy, -COOH, -SO3H, chlorine or bromine, P = a group (II), A, B independently = H, C1-C6 alkyl, phenyl, or together form a cyclopentene or cyclohexene ring, which comprise the double bond to which A and B are bonded, Q = a chemical bond, a -O-, -NR -, -S-, -OCO-, -OCOO-, -OCONR -, -NR CO-, -NR COO-, -NR CONR -, -CO-, -COO-, -CONR -, -SO2-O-, -SO2NR -, -O-SO2- or -NR SO2- group, n = 0, 1, 2 or 3 and R = H, optionally-substituted C1-C30 alkyl, C5-C8 cycloalkyl, aryl or heteroaryl.
Abstract:
The current invention relates to a perylene-3,4-dicarboxylic anhydride, substituted in the 9-position, of the general formula III wherein Z is bromine or cyano, and processes for preparing 9-bromoperylene-3,4-dicarboxylic anhydride and 9-cyanoperylene-3,4-dicarboxylic anhydride.
