| abstract |
The present invention provides a polymer comprising a repeating unit represented by the formula (1).n n n Formula 1n n n n n n n n In the above formula,n n n A 1 represents a divalent group having a bonding distance ratio [bonding distance of C (α) -A1 / bonding distance of C (α) -C (β)] of 1.10 or more,n n n R 1 , R 2 , R 3 , R 4 , R 5 and R 6 each independently represent a hydrogen atom, an alkyl group, an alkyloxy group, an aryloxy group, an arylalkyloxy group, or the like.n n n The polymers are useful as luminescent materials, charge transfer materials and the like. |
