Patent ID: 7193021

Claim:
A copolymer for electronic and opto-electronic applications made by a catalytic reaction between a functional thiophene monomer of formula II and an aniline derivative of formula III with an organic metal compound as the catalyst having a general formula I: Wherein: m and n each independently represents an integer and m≧1 and n≧2. R1, R2, R3, R4, R5, R6 and R7 each independently represents, hydrogen atom (but at least one of R1, R2, R3, R4, R5, R6 and R7 is not hydrogen), alkyl, alkenyl, alkynyl, aryl, alkylaryl, CN, CF 3 , C n F 2n+1 , trifluorovinyl, CO 2 R, C(O)R, NR 2 , NO 2 , OR, halo, heteroaryl, substituted aryl, substituted heteroaryl or a heterocyclic group, and additionally, or alternatively, any one or more of R1 and R2 or R7 and R5, or R5 and R3, or R3 and R4, or R4 and R6 together form, independently, a fused 5- to 6-member cyclic group, wherein said cyclic group is cycloalkyl, cycloheteroalkyl, aryl, or heteroaryl, and wherein the fused 5- to 6-member cyclic group cyclic group may be optionally substituted with one or more of alkyl, alkenyl, alkynyl, alkylaryl, CN, CF 3 , C n F 2n+1 , trifluorovinyl, CO 2 R, C(O)R, NR 2 , NO 2 , OR, halo; each R is independently H, alkyl, alkenyl, alkynyl, alkylaryl, and aryl. X represents a halide atom.
