Provided are organometallic complexes that can exhibit phosphorescence. One of the novel organometallic complexes is represented by General Formula (G1). In General Formula (G1), R1 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, R2 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.
提供了可以展现
磷光的有机
金属配合物。其中一种新颖的有机
金属配合物由通式(G1)表示。在通式(G1)中,R1代表具有1至6个碳原子的烷基基团、具有5至8个碳原子的环烷基基团,该基团可以有取代基,以及具有7至10个碳原子的芳基烷基基团,该基团可以有取代基。此外,R2代表具有1至6个碳原子的烷基基团、具有5至8个碳原子的环烷基基团,该基团可以有取代基,以及具有6至12个碳原子的芳基基团,该基团可以有取代基。此外,Ar代表具有6至13个碳原子的芳亚基基团,该基团可以有取代基。进一步地,M代表第9族元素或第10族元素。
