Patent ID: 8293380

Claim:
A polymer compound having one or more repeating units of the following formula (A) and containing further a structure of the following formula (B) as a complete structure: —Ar— (A) wherein, Ar represents an arylene group, divalent heterocyclic group, divalent aromatic amine group or divalent group having a metal complex structure wherein, A ring and B ring represent each independently an aromatic ring optionally having a substituent, X represents —C(═O)—, —S(═O)—, —S(═O) 2 —, —P(═O)(R 1 )—, —C(R 1 )(R 2 )—, —C(R 2 )(R 2 )—, —B(R 1 )—, R* represents a hydrogen atom or monovalent or divalent group, R 1 represents a hydrogen atom or monovalent group, and R 2 represents a monovalent group having a hetero atom, and when R 1 and R 2 are present each in plural number, they may be the same or different, wherein the polystyrene reduced number average molecular weight is 10 3 to 10 8 , and wherein the polymer compound contains a structure of the above-described formula (B) at any of the main chain and end of the polymer compound.
