UNSYMMETRICAL BENZOTHIADIAZOLE-BASED RANDOM COPOLYMERS

Abstract:

A random copolymer comprising the monomer units A and B. In this random copolymer A comprises ##STR00001## and B comprises ##STR00002## Additionally, R1 R2, R3 and R4 are side chains independently selected from the group consisting of: H, Cl, F, CN, alkyl, alkoxy, alkylthio, ester, ketone and aryl groups. X1 and X2 are identical and selected from the group consisting of: H, Cl, F, CN, alkyl, alkoxy, ester, ketone, amide and aryl groups.
