POLYMERIC COMPOUND AND LIGHT-EMITTING ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polymeric compound useful for manufacturing a light-emitting element excellent in a drive voltage.SOLUTION: A metal complex includes, as ligands: a specific compound having a five-member cyclic triazole group bonded to an aromatic group; and a polymeric compound prepared by condensation polymerization of formula (Y1) and formula (Y2) and having a triazole group. In the formulae, Arrepresents an aromatic hydrocarbon group; Rrepresents an alkyl group or the like; p is an integer of 1 or more and at least one Ris bonded to a carbon atom adjacent to a carbon atom that forms a bond with another structural unit; and Arrepresents a divalent heterocyclic group or the like.
