Abstract:
An electroluminescent polymer, represented by the following formula (1): wherein X1 to X5 are independently a hydrogen atom, a linear alkyl or alkoxy group having 1 to 40 carbon atoms, a branched alkyl or alkoxy group having 3 to 40 carbon atoms, a cyclic alkyl group having 5 to 40 carbon atoms, a silyl group, or an aromatic group having 6 to 14 carbon atoms which is unsubstituted or substituted with at least one selected from the group consisting of an alkoxy group having 1 to 40 carbon atoms and an amine group, wherein at least one of the X substituents is a linear alkoxy group having 1 to 40 carbon atoms, or a branched alkoxy group having 3 to 40 carbon atoms; and wherein the variable â€œnâ€  is a number such that the number average molecular weight of the electroluminescent polymer is about 10,000-1,000,000, and the molecular weight distribution thereof is about 1.5-5.0.
