<p>The present invention provides a novel metal complex compound represented by the following general formula (1), and an organic electroluminescence element which has a high efficiency of light emission and a long lifetime, wherein one of organic thin film layers including at least a light emitting layer between an anode and a cathode, a least one of the organic thin film layers contains the metal complex compounds.
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(L 1 ) m M(L 2 ) n €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein M represents Ir, Pt and Rh; L 1 and L 2 represents mutually different bidentate ligands; (L 1 ) m M as a partial structure is represented by general formula (2) and M(L 2 ) n as a partial structure is represented by general formula (3): and m and n are each an integer of 1 or 2, provided that m+n is a integer of 2 or 3.
wherein ring A1 represents an aromatic hetrocyclic ring group; and ring B1 represents an aryl group, provided that the ring A1 and the ring B1 are covalently linked to each other via Z which represents a single bond or the like.
wherein R 1 , R 2 , R 2 ' and R 3 each independently represent an alkyl group or the like; R 1 and Rz, R 1 and R 2 ', Rz and R 2 ', Rz and R 3 , and R 2 ' and R 3 may combine with each other to form a cyclic structure; and Y represents a group represented by O or S.</p> |
