Carbazole-based random copolymer

摘要

PROBLEM TO BE SOLVED: To provide a polymeric organic light-emitting material which is high in solubility, stability and luminous efficiency.;SOLUTION: The polymeric organic light-emitting material consists of a carbazole-based random copolymer of (a) component represented by general formula (1) and (b) another component represented by general formula (2). In these general formulas, R_1a and R_1b are each independently H, 1-30C alkyl, 2-30C aromatic cyclic group or the like; R_2a and R_2b are each independently (substituted) 1-30C alkyl, (substituted) 2-30C aromatic cyclic group or the like.;COPYRIGHT: (C)2008,JPO&INPIT
