Patent ID: 8808878

Claim:
A compound represented by the following general formula (1): wherein C^N (indicated by A) represents a cyclometalating ligand, M represents a transition metal atom, X1 represents a nitrogen atom or a sulfur atom, X2 represents a nitrogen atom, a sulfur atom, or a phosphorous atom, wherein the phosphorous atom is connected to two R1 or two R2 respectively, R1 and R2 each independently represent a straight, branched, or cyclic alkyl group, an aryl group, an aralkyl group, or an ether group, which groups may have a substituent, R3 represents a straight, branched, or cyclic alkyl group, an alkenyl group, an alkynyl group, an aryl group, an aralkyl group, an aliphatic, aromatic, or cyclic amino group, a phosphino group, a boryl group, an alkylthio group, an arylthio group, an alkoxy group, an aryloxy group, an ether group, or an imino group, which groups may have a substituent, and m and n each independently represent an integer of not less than 1, and a total of m and n is not more than the largest number of ligands that can coordinate with M.
