To provide a polymer organic light-emitting material having excellent solubility, high stability, and high light emission efficiency. A carbazole random copolymer containing a component (a) represented by the following general formula (1) and a component (b) represented by a different general formula (2). [Wherein, R 1a and R 1b are each independently a hydrogen atom, an alkyl group having 1 to 30 carbon atoms, an aromatic cyclic group having 2 to 30 carbon atoms, etc. R 2a and R 2b are each independently And an alkyl group having 1 to 30 carbon atoms which may have a substituent, an aromatic cyclic group having 2 to 30 carbon atoms which may have a substituent, and the like. ] [Selection figure] None |
