Abstract:
1. A metal complex compound having a metal-carbene bond represented by following general formula (1): [In general formula (1), M represents an iridium atom, L 1 and L 2 represent bidentate ligands different from each other, a partial structure represented by (L 1 ) m M is represented by following general formula (2), a partial structure represented by M(L 2 ) n is represented by following general formula (3), m represents an integer of 0 to 2, n represents an integer of 1 to 3, and m+n represents a valence of the metal represented by M {In general formula (2), N and C represent nitrogen atom and carbon atom, respectively, ring A1 represents an aromatic heterocyclic group having 3 to 50 nuclear atoms including nitrogen atom which may have substituents, ring B1 represents an aryl group having 6 to 50 nuclear carbon atoms which may have substituents, and ring A1 and ring B1 are bonded with covalent bonds via Z, wherein Z represents a single bond, —O—, —S—, —CO—, —(CR′R″) (R′ and R″ each independently represent hydrogen atom, an aryl group having 6 to 50 nuclear carbon atoms which may have substituents, an aromatic heterocyclic group having 3 to 50 nuclear atoms which may have substituents or an alkyl group having 1 to 50 carbon atoms which may have substituents, a represents an integer of 1 to 10, and the atoms and the groups represented by R′ and R″ may be a same with or different from each other)} {In general formula (3), B represents boron atom, L 3 and L 4 each represent a crosslinking group having a covalent bond (shown by a solid line) and a coordinate bond (shown by an arrow), at least one of L 3 and L 4 represents an aromatic heterocyclic group having 3 to 50 nuclear atoms and nitrogen atom which has a coordinate bond with carbene carbon atom and may have substituents, R a and R b each independently represent hydrogen atom, an alkyl group having 1 to 50 carbon atoms which may have substituents, an alkenyl group having 2 to 50 carbon atoms which may have substituents, an aryl group having 6 to 50 nuclear carbon atoms which may have substituents or an aromatic heterocyclic group having 3 to 50 nuclear atoms which may have substituents, and groups represented by L 3 , L 4 , R a and R b may be bonded to each other to form a cyclic structure}].
