Patent ID: 7667228

Claim:
A metal complex compound having a partial structure represented by the following general formula (I): wherein R 1 to R 3 and R 5 each independently represents a hydrogen atom, a cyano group, a nitro group, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted amino group, a substituted or unsubstituted alkoxyl group having 1 to 20 carbon atoms, a substituted or unsubstituted alkylsilyl group having 1 to 20 carbon atoms, a substituted or unsubstituted acyl group having 1 to 20 carbon atoms or a substituted or unsubstituted aromatic group having 1 to 30 carbon atoms; R 4 represents a cyano group, a nitro group, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted amino group, a substituted or unsubstituted alkoxyl group having 1 to 20 carbon atoms, a substituted or unsubstituted alkylsilyl group having 1 to 20 carbon atoms, a substituted or unsubstituted acyl group having 1 to 20 carbon atoms or a substituted or unsubstituted aromatic group having 1 to 30 carbon atoms; R 1 and R 2 bond to each other to form a ring structure selected from the group consisting of benzene, pyridine, naphthalene, benzothiazole, quinoline, thiazole, furan, benzofuran and 9.9-dimethylfluorene; a pair of one R 3 and R 4 and a pair of R 4 and one R 5 may bond to each other to form a ring structure; p and q each independently represents an integer of 0 to 3; p+q being 2 or 3; when p is an integer of 2 or greater, the plurality of R 3 may bond to each other to form a ring structure; when q is an integer of 2 or greater, the plurality of R 5 may bond to each other to form a ring structure, with the provisos that when p is 0 and q is 2, the plurality of R 5 do not bond to each other to form a ring structures and when p is 0, q is 2, and R 1 and R 2 bond to each other to form a ring structure, the ring structure is not substituted with phenyl; and M represents a metal atom selected from the group consisting of iridium (Ir) atom, rhodium (Rh) atom, and platinum (Pt) atom.
