TETRAAROXYPERYLENE-3,4,9,10-TETRACARBOXYLIC ACID POLYIMIDES

摘要

The invention pertains to tetraaroxyperylene-3,4,9,10-tetracarboxylic acid polyimides (I) (R<1>: like or different alkyl radicals that can be substituted by cyano, nitro, halogen, C1-C18 alkoxy, C5-C7 cycloalkyl and/or C1-C18 alkyl and can contain up to 24 C atoms in each case; R<2>: C2-C30 alkylene groups whose carbon chain can be interrupted by 1 to 10 oxygen atoms in ether function or by a phenylene or cyclohexylene group, or possibly by C6-C30 arylene or cyclohexylene radicals bridged by C1-C10 alkylene or oxygen; n: 2 to 100), a method for preparing them, their use, as well as tetraaroxyperylene-3,4,9,10-tetracarboxylic acid dianhydrides as their intermediate products.
