Patent ID: 7960500

Claim:
A polymer as represented by Formula 1 below: where x is from 0.001 to 0.99; n is from 10 to 150; Ar 1 is a material selected from the group consisting of a substituted or unsubstituted C6-C30 arylene group, a substituted or unsubstituted C2-C30 heteroarylene group, a substituted or unsubstituted C2-C30 hetero ring group, and a substituted or unsubstituted C2-C30 vinylene group; R 1 and R 2 are each independently H, a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C4-C20 cycloalkyl group, or a substituted or unsubstituted C1-C20 alkoxy group, and R1 and R2 can be connected to each other to form a ring; R 3 is H, an alkyl group, an alkoxy group, an ester group, a cyano group, an aryl group, a heteroaryl group, a cyclic group, a heterocyclic group, or a fused aromatic group; and R 4 is a material selected from the group consisting of H, an alkyl group, an alkoxy group, an ester group, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C2-C30 heteroaryl group, a substituted or unsubstituted C2-C30 hetero ring group, a fused aromatic group, and a triphenylamine derivative.
