Abstract:
1. A light-emitting polymer represented by the formula I: wherein X and U are independently selected from the group consisting of a single bond, —O—, —S—, —CO—, —Si(R′)(R″)—, —N(R′)— and —C(R′)(R″)—, and at least one of X and U is not a single bond; A, B, C and D are independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted C1-C30 alkylene group, a substituted or unsubstituted C2-C30 alkenylene group, a substituted or unsubstituted C3-C20 cyclic alkylene group, a substituted or unsubstituted C6-C30 arylene group, and a substituted or unsubstituted C2-C30 heteroarylene group; R m is a degree of polymerization and is a real number from 5 to 1,000.
