A novel organometallic complex with high emission efficiency is provided. The organometallic complex, which is represented by General Formula (G1), includes iridium and a ligand including an aryl group including a cyano group at the 1-position of a benzimidazole skeleton and a phenyl group at the 2-position of the benzimidazole skeleton. (In the formula, Ar1 represents an aryl group having one or more substituents and 6 to 13 carbon atoms, and Arl includes at least one cyano group as the substituent. Each of R1 to R8 separately represents any of hydrogen, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 6 carbon atoms, a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, a substituted or unsubstituted heteroaryl group having 3 to 12 carbon atoms, and a cyano group.)
提供了一种具有高发射效率的新型有机金属配合物。该有机金属配合物由通用公式(G1)表示,包括铱和一种配体,其中该配体包括一个芳基团,在苯并咪唑骨架的1-位置带有一个氰基团和在苯并咪唑骨架的2-位置带有一个苯基团。(在公式中,Ar1代表具有一个或多个取代基和6到13个碳原子的芳基团,Arl至少包括一个氰基作为取代基。R1至R8中的每一个分别代表氢、具有1到6个碳原子的取代或未取代烷基基团、具有3到6个碳原子的取代或未取代环烷基基团、具有6到13个碳原子的取代或未取代芳基基团、具有3到12个碳原子的取代或未取代杂环芳基基团和一个氰基。)
