Patent ID: 8558007

Claim:
A polymer comprising a polymeric unit represented by Formula 1 below: wherein each Ar is independently selected from a substituted or unsubstituted C 6 -C 30 arylene group and a substituted or unsubstituted C 3 -C 30 heteroarylene group; a is an integer ranging from 1 to about 3; each of R 1 to R 14 and R 21 to R 27 is independently selected from a hydrogen atom, a halogen atom, a hydroxyl group, an amino group, a cyano group, a carboxylic acid group, a substituted or unsubstituted C 1 -C 30 alkyl group, a substituted or unsubstituted C 2 -C 30 alkenyl group, a substituted or unsubstituted C 2 -C 30 alkynyl group, a substituted or unsubstituted C 1 -C 30 alkoxy group, a substituted or unsubstituted C 6 -C 30 aryl group, a substituted or unsubstituted C 3 -C 30 heteroaryl group, a group represented by —N(Q 1 )(Q 2 ), and a group represented by —Si(Q 3 )(Q 4 )(Q 5 ), wherein each of Q 1 to Q 5 is independently selected from a hydrogen atom, a halogen atom, a hydroxyl group, an amino group, a cyano group, a carboxylic acid group, a substituted or unsubstituted C 1 -C 30 alkyl group, a substituted or unsubstituted C 2 -C 30 alkenyl group, a substituted or unsubstituted C 2 -C 30 alkynyl group, a substituted or unsubstituted C 1 -C 30 alkoxy group, a substituted or unsubstituted C 6 -C 30 aryl group, and a substituted or unsubstituted C 3 -C 30 heteroaryl group; n is an integer ranging from 1 to about 5; and each “*” indicates a point of attachment to the same or a different polymeric unit represented by Formula 1.
