Provided are organometallic complexes that can exhibit phosphorescence. One of the novel organometallic complexes is represented by General Formula (G1). In General Formula (G1), R
1
represents any of an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms which may have a substituent, and an aralkyl group having 7 to 10 carbon atoms which may have a substituent. In addition, R
2
represents any of an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms which may have a substituent, and an aryl group having 6 to 12 carbon atoms which may have a substituent. Further, Ar represents an arylene group having 6 to 13 carbon atoms which may have a substituent. Further, M represents a Group 9 element or a Group 10 element.
提供了能够表现出磷光的有机金属配合物。其中一种新型有机金属配合物由通用式(G1)表示。在通用式(G1)中,R1代表具有1至6个碳原子的烷基,具有5至8个碳原子的环烷基,可能具有取代基,以及具有7至10个碳原子的芳基烷基,可能具有取代基。此外,R2代表具有1至6个碳原子的烷基,具有5至8个碳原子的环烷基,可能具有取代基,以及具有6至12个碳原子的芳基,可能具有取代基。进一步地,Ar代表具有6至13个碳原子的芳撑基,可能具有取代基。此外,M代表第9族元素或第10族元素。
