Abstract:
Provided is a polymer comprising a repeating unit represented by formula (1), wherein, A1 represents a divalent group in which the bond distance ratio (bond distance of C(α)-A1/bond distance of C(α)-C(β)) is 1.10 or more; R1, R2, R3, R4, R5, and R6, each independently represent a hydrogen atom, alkyl group, alkyloxy group, aryloxy group, arylalkyloxy group, etc. The polymer is useful as a light-emitting material, a charge transporting material, etc.
