Patent ID: 7955716

Claim:
A metal coordination compound represented by any one of Formulae I-(1) to I-(6), (in the formulae, M is Ir, Rh, Ru, Os, Pd, or Pt, and n is 2 or 3; when M is Ir, Rh, Ru, or Os and n is 2, another bidentate ligand further bonds to M; ring A is a cyclic compound containing a nitrogen atom bonded to M; X 1 to X 7 may be any of a hydrogen atom, a halogen atom, a cyano group, a nitro group, a C1 to C22 straight-chain, cyclic, or branched alkyl group or a corresponding halogen-substituted alkyl group in which a part or all of the hydrogen atoms are substituted by a halogen atom, a C6 to C21 aryl group, a C2 to C20 heteroaryl group, or a C7 to C21 aralkyl group, or a corresponding halogen-substituted aryl group, halogen-substituted heteroaryl group, or halogen-substituted aralkyl group in which a part or all of the hydrogen atoms are substituted by a halogen atom, X 1 to X 7 may be identical to or different from each other, and ring A may have a substituent that is the same as the groups defined by X 1 to X 7 ) wherein in Formulae I-(1) to I-(6) at least one of X 1 to X 7 and the substituent of ring A defined as being the same as X 1 to X 7 is a fluorine atom or a trifluoromethyl group.
