Patent ID: 7985810

Claim:
A polymer compound comprising a repeating unit of the following formula (1) and at least one of a repeating unit of the following formula (2) and a repeating unit of the following formula (70) Ar 1 and Ar 2 represent each independently an arylene group, divalent heterocyclic group or divalent aromatic amine group, Ar 3 represents an aryl group, monovalent heterocyclic group or monovalent aromatic amine group, Z represents —CR 1 ═CR 2 — or —C≡C—, R 1 and R 2 represent each independently a hydrogen atom, alkyl group, aryl group, monovalent heterocyclic group or cyano group, m represents 0 or 1, wherein, a ring A and a ring B represent each independently an aromatic hydrocarbon ring optionally having a substituent, and at least one of the ring A and the ring B is an aromatic hydrocarbon ring having two or more benzene rings condensed, two bonds are present on the ring A and/or the ring B, and Rw and Rx represent each independently a hydrogen atom, alkyl group, alkoxy group, alkylthio group, aryl group, aryloxy group, arylthio group, arylalkyl group, arylalkoxy group, arylalkylthio group, arylalkenyl group, arylalkynyl group, amino group, substituted amino group, silyl group, substituted silyl group, halogen atom, acyl group, acyloxy group, imine residue, amide group, acid imide group, monovalent heterocyclic group, carboxyl group, substituted carboxyl group or cyano group, and Rw and Rx may be mutually connected to form a ring, wherein, a ring C and a ring D represent each independently an aromatic ring, the ring C or the ring D optionally have a substituent selected from the group consisting of an alkyl group, alkoxy group, alkylthio group, alkylsilyl group, alkylamino group, aryl group, aryloxy group, arylalkyl group, arylalkoxy group, arylalkenyl group, arylalkynyl group, arylamino group, monovalent heterocyclic group or cyano group, when there are two or more substituents, they may be the same or different, and E represents O or S.
