SEMICONDUCTING MATERIALS BASED ON NAPHTHALENEDIIMIDE-VINYLENE-OLIGOTHIOPHENE-VINYLENE POLYMERS

摘要

The present invention provides a polymer comprising a unit of formula, wherein R1 and R2 are independently from each other C1-30-alkyl, C2-30-alkenyl, C2-30-alkynyl, phenyl or a 5 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, OH, NH2, NH(C1-20-alkyl), N(C1-20-alkyl)2, NHC(O)(C1-20-alkyl), S(O)2OH, CHO, C(O)C1-20-alkyl, C(O)OH, C(O)OC1-20-alkyl, C(O)NH2, CO(O)NHC1-20-alkyl, C(O)N(C1-20-alkyl)2, OC1-20-alkyl, OC(O)C1-20-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 5 C1-16-alkyl groups, is 1, 2 or 3 and n is an integer from 2 to 10'000, a process for the preparation of the polymer and an electronic device comprising the polymer.
