Patent ID: 8877349

Claim:
An organometallic complex represented by Formula 3: M is Ir, Os, Pt, Pb, Re, Ru or Pd and has oxidation state of 3; CyN is a substituted or unsubstituted C 3 -C 60 heterocyclic group including nitrogen which is combined with M, 1,2,4-triazole including nitrogen which is combined with M, or a substituted or unsubstituted C 3 -C 60 heteroaryl group including nitrogen which is combined with M; CyC is a substituted or unsubstituted C 4 -C 60 cyclic group including carbon which is combined with M, a substituted or unsubstituted C 3 -C 60 heterocyclic group including carbon which is combined with M, a substituted or unsubstituted C 6 -C 60 aryl group including carbon which is combined with M, or a substituted or unsubstituted C 3 -C 60 heteroaryl group including carbon which is combined with M; CyN—CyC indicates a cyclometalating ligand which is a monoanionic bidentate ligand and combined with M through the nitrogen (N) of the CyN and the carbon (C) of the CyC; X is NR 0 , O, or S, where R 0 is hydrogen, a halogen atom, a carboxyl group, or a C 1 -C 20 alkyl group; R 1 , R 2 , R 3 , R 5 , R 6 , R 7 , R 8 , and R 9 are each independently hydrogen, a halogen atom, a carboxyl group, an amino group, a nitro group, a cyano group, a substituted or unsubstituted C 1 -C 20 alkyl group, a substituted or unsubstituted C 1 -C 20 alkoxy group, a substituted or unsubstituted C 2 -C 20 alkenyl group, a substituted or unsubstituted C 2 -C 20 alkynyl group, a substituted or unsubstituted C 1 -C 20 heteroalkyl group, a substituted or unsubstituted C 6 -C 30 aryl group, a substituted or unsubstituted C 7 -C 30 arylalkyl group, a substituted or unsubstituted C 3 -C 30 heteroaryl group, or a substituted or unsubstituted C 3 -C 30 heteroarylalkyl group and at least two of R 1 , R 2 , R 3 , R 5 , R 6 , R 7 , R 8 , and R 9 may be fused into a 5 to 7-membered ring; and n is an integer in a range of 0 to 30.
