Claim:
A heteronuclear copper (I)-iridium (III) complex represented by a formula selected from the group consisting of Formulae 1 through 3: where A-X—B is a mononegative bidentate auxiliary ligand containing a hetero atom X; X is N, P, S, or O; CyN is 1,2,4-triazole, a substituted or unsubstituted C 3 -C 60 hetero ring group including nitrogen bound to iridium (III), or a substituted or unsubstituted C 3 -C 60 heteroaryl group including nitrogen bound to iridium; CyC is a substituted or unsubstituted C 4 -C 60 cyclic group including carbon bound to iridium, a substituted or unsubstituted C 3 -C 60 hetero ring group including carbon bound to iridium, a substituted or unsubstituted C 6 -C 60 aryl group including carbon bound to iridium, or a substituted or unsubstituted C 3 -C 60 heteroaryl group including carbon bound to iridium; and CyN-CyC is a cyclometalating ligand coordinated to iridium via the nitrogen of the CyN and the carbon of the CyC, and, alternative to the above definition of CyN and CyC, CyN-CyC is optionally Where R 11 , R 12 , R 13 and R 14 are each independently selected from the group consisting of hydrogen, a halogen atom, —OR, —N(R) 2 , —P(R) 2 , —POR, —PO 2 R, —PO 3 R, —SR, —Si(R) 3 , —B(R) 2 , —B(OR) 2 , —C(O)R, —C(O)OR, —C(O)N(R), —CN, —NO 2 , —SO 2 , —SOR, —SO 2 R, —SO 3 R, a C 1 -C 20 alkyl group, and a C 6 -C 20 aryl group, wherein R is selected from the group consisting of hydrogen, a halogen atom, a substituted or unsubstituted C 1 -C 20 alkyl group, a substituted or unsubstituted C 1 -C 10 alkoxy group, a substituted or unsubstituted C 2 -C 20 alkenyl group, a substituted or unsubstituted C 2 -C 20 alkenyl group, a substituted or unsubstituted C 1 -C 20 heteroalkyl, a substituted or unsubstituted C 6 -C 40 aryl group, a substituted or unsubstituted C 7 -C 40 arylalkyl group, a substituted or unsubstituted C 7 -C 40 alkylaryl group, a substituted or unsubstituted C 2 -C 40 heteroaryl group, and a substituted or unsubstituted C 3 -C 40 heteroarylalkyl group.
