Patent ID: 8441003

Claim:
A phosphorescent polymer compound comprising structural units that are derived from a compound represented by Formula (1): wherein R 1 to R 8 are each independently a hydrogen atom, a halogen atom, a cyano group, a C1-10 alkyl group, a C6-10 aryl group, a C1-15 heteroaryl group, an amino group optionally substituted with a C1-10 alkyl group, a C1-10 alkoxy group, a silyl group optionally substituted with a C1-10 alkyl group, or a group having a radically polymerizable functional group, and one of R 1 to R 8 is a group having a radically polymerizable functional group; the group having a radically polymerizable functional group has a divalent group which has the longest chain composed of 1 to 5 atoms between the group having a radically polymerizable functional group and the carbon atom on the benzene or pyridine ring coordinated to iridium, the group having a radically polymerizable functional group with the divalent group is at least one selected from the group consisting of those represented by Formulae (a1), (a2) and (a4) to (a7) below L is a ligand represented by any of Formulae (1a) to (1i) below, and the two ligands L may be the same or different from each other; and the five-membered ring in the ligand L may have a substituent group selected from the group consisting of C1-10 alkyl groups, amino groups optionally substituted with a C1-10 alkyl group, and C1-10 alkoxy groups; wherein R 9 to R 12 are each independently a hydrogen atom, a halogen atom, a cyano group, a C1-10 alkyl group, an amino group optionally substituted with a C1-10 alkyl group, a C1-10 alkoxy group, or a silyl group optionally substituted with a C1-10 alkyl group.
