Patent ID: 8278411

Claim:
A polymer comprising a polymeric unit represented by Formula 1 below: wherein, in Formula 1, each Ar 1 , Ar 2 and Ar 3 is independently a substituted or unsubstituted C 6 -C 30 arylene group or a substituted or unsubstituted C 3 -C 30 heteroarylene group; a, b and c are each independently an integer from 1 to 3; each Ar 1 in —(Ar 1 ) a — is identical to or different from any other Ar 1 , b groups of —Ar 2 — in —(Ar 2 ) b — are identical to or different from each other and c groups of —Ar 3 — in —(Ar 3 ) c — are identical to or different from each other; R 1 to R 22 and R 31 to R 37 are independently a hydrogen atom, a halogen atom, a hydroxyl group, an amino group, a cyano group, a carboxyl 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 3- to 30-membered heteroaryl group, a group represented by —N(Q 1 )(Q 2 ) or a group represented by —Si(Q 3 )(Q 4 )(Q 5 ), wherein Q 1 to Q 5 are each independently a hydrogen atom, a halogen atom, a hydroxyl group, an amino group, a cyano group, a carboxyl 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 or a substituted or unsubstituted C 3 -C 30 heteroaryl group; n is an integer from 0 to 5; and each “*” indicates a point of attachment to an identical or a different polymeric unit.
