Abstract
It is an object of the present invention to provide an organometallic complex that can emit phosphorescence. In the following general formula (G1), X represents —O— or —N(R)—. Rto Reach represent any of hydrogen, an alkyl group or a cycloalkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, an alkoxycarbonyl group having 1 to 6 carbon atoms, an acyl group having 1 to 6 carbon atoms, an acyloxy group having 1 to 6 carbon atoms, a halogen group, a haloalkyl group, and an aryl group having 6 to 12 carbon atoms. In addition, Rrepresents any of an alkyl group or a cycloalkyl group having 1 to 6 carbon atoms, an acyl group having 1 to 6 carbon atoms, an aryl group having 6 to 12 carbon atoms, and a heteroaryl group having 4 to 10 carbon atoms. Moreover, M represents an element belonging to Group 9 or 10.
