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.
本文提供了可显示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式(G1)表示。在通式(G1)中,R1 代表具有 1 至 6 个碳原子的烷基、具有 5 至 8 个碳原子且可能具有取代基的环烷基和具有 7 至 10 个碳原子且可能具有取代基的芳烷基中的任意一种。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(可带有取代基)和具有 6 至 12 个碳原子的芳基(可带有取代基)中的任意一种。此外,Ar 代表具有 6 至 13 个碳原子的芳烯基团,该基团可具有取代基。此外,M 代表第 9 族元素或第 10 族元素。
