PROBLEM TO BE SOLVED: To provide a new compound suitable as a phosphorescence radiator, capable of being easily produced, capable of being given from a liquid, and improved in such a defect that conventional phosphorescence radiators require complicated procedures in synthesis and crystallization of their ligands.;SOLUTION: A polynuclear metal complex expressed by general formula (I): (L_mMe-H_L)_n-X_L (Me is a transition metal; L is a bidentate chelate-forming ligand; H_L is a bidentate chelate-forming ligand which complexes a transition metal Me into a chelate state and is additionally combined with a linker X_L; X_L is an n-functional linker and is covalently bonded to n pieces of auxiliary ligands H_Ls; m is 1-3; and n is 2-6) is provided.;COPYRIGHT: (C)2004,JPO
