ABSTRACT:
A main chain-type or side chain-type polymeric compound having a structure wherein at least one metal complex segment having a plurality ligands is introduced into a main chain or a side chain is provided. In the case where the polymeric compound is the main chain-type polymeric compound, the metal complex segment has at least one ligand constituting a polymer main chain of the polymeric compound and having a carbon atom and oxygen atom bonded to a metal atom. On the other hand, in the case where the polymeric compound is the side chain-type polymeric compound, a polymer main chain thereof has a conjugated structure, preferably a conjugated double bond. A ligand for the polymeric compound includes a chain or cyclic ligand, of which a bidentate ligand having an organic cyclic structure is preferred, and the ligand has at least one carbon atom or oxygen atom and is bonded to a center metal atom, preferably iridium, via the carbon atom or oxygen atom. In a case of forming a luminescence layer by using the polymeric compound as a luminescent material, a resultant organic luminescence device is less liable to cause a concentration extinction and is a high-luminescence efficiency device excellent in stability.
