Abstract:
It is an object of the present invention to provide a substance capable of emitting phosphorescence. In addition, it is an object of the present invention to provide a light-emitting element that is excellent in chromaticity. One aspect of the present invention is an organometallic complex having a structure represented by a general formula (1). In the general formula (1), R1 to R4 are each any one of hydrogen, a halogen element, an acyl group, an alkyl group, an alkoxyl group, an aryl group, a cyano group, and a heterocyclic group. In addition, R5 to R13 are each any one of hydrogen, an acyl group, an alkyl group, an alkoxyl group, an aryl group, a heterocyclic group, and an electron-withdrawing group. An organometallic complex having such a structure can emit phosphorescence with higher emission intensity.
