Patent ID: 8247086

Claim:
An organometallic complex comprising a structure represented by a general formula (G10): wherein R 1 represents an alkyl group having 1 to 4 carbon atoms; R 2 and R 3 each represent any one of hydrogen and an alkyl group having 1 to 4 carbon atoms; Ar represents any one of formulas (G7) to (G9); R 7 and R 8 each represent an alkyl group having 1 to 4 carbon atoms; M is a center metal selected from Group 9 element; α represents a position of carbon which bonds the center metal in the arylene group; L represents a monoanionic ligand; and n is 2; wherein the monoanionic ligand is any one of a monoanionic bidentate chelate ligand having a β-diketone structure, a monoanionic bidentate chelate ligand having a carboxyl group, a monoanionic bidentate chelate ligand having a phenolic hydroxyl group, and a monoanionic bidentate chelate ligand in which two ligand elements are both nitrogen.
