摘要

The present invention provides a polymer comprising a unit of formula (1), wherein R1 and R2 are independently from each other C1-30 -alkyl, C2-30 -alkenyl, C2-30 -alkynyl, phenyl or a to 8 membered heterocyclic ring system, wherein each of the C1-30-alkyl, C2-30-alkenyl or C2-30-alkynyl group may be substituted with 1 to 10 substituents independently selected from the group consisting of halogen, -CN, -NO2, -1 OH, -NH2, -NH(C1-20 -alkyl), -N(C1-20 -alkyl) 2, -NH-C(O)-(C -20 -alkyl), -S(O)2 OH, -CHO, -C(O)-C1 -20 -alkyl, -C(O)OH, -C(O)-OC1-20 -alkyl, -C(O)NH2, -CO(O)NH-C1-20-alkyl, -C(O)N(C1-20 -alkyl)2, -O-C1-20 -alkyl, -O-C(O)-C -20 -alkyl, -SiH3, SiH2 (C1-20 -alkyl), SiH(C1-20-alkyl)2,Si(C1-20 -alkyl)3, C4-8 -cycloalkyl, phenyl and a 5 to 8 membered heterocyclic ring system, and phenyl and the 5 to 8 membered heterocyclic ring system may be substituted with 1 to C1-16 -alkyl groups, o is 1, 2 or 3 2 and n is an integer from 2 to 10'000, 30 a process for the preparation of the polymer and an electronic device comprising the polymer.
