Provided are main-chain type or side-chain type high-molecular compounds wherein at least one metal complex moiety bearing two or more ligands in the structure is introduced into the main chain or the side chain. In the main-chain type high-molecular compound, at least one ligand of the metal complex moiety participates in constituting the main chain of the compound and the carbon or oxygen atom of the ligand is bonded to the metal atom, while in the side-chain type high-molecular compound, the main chain has a conjugated structure, preferably conjugated double bonds. The ligands are preferably bidentate ones having organic cyclic structures, though they include linear and cyclic ones. Each ligand is bonded to the central metal atom, preferably iridium, through at least one carbon or oxygen atom constituting the ligand. Organic luminescent devices equipped with light-emitting layers containing the high-molecular compounds as the luminescent material little cause concentration quenching and exhibit high luminous efficiency and excellent stability.
