Organic Compound, Light-Emitting Element, Light-Emitting Device, Electronic Device, and Lighting Device

摘要

An organic compound having a low HOMO level and a high hole-transport property is provided. The organic compound is represented by Formula (G1), where Ar1 represents a substituted or unsubstituted fluorenyl group, Ar2 represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, and A1 represents any one of a substituted or unsubstituted dibenzofuranyl group and a substituted or unsubstituted dibenzothiophenyl group. The low HOMO level and the high hole-transport property of the organic compound allow the formation of an exciplex with another organic compound, which leads to a highly efficient light-emitting element in the presence of a phosphorescent compound due to the effective overlapping between the emission of the exciplex and the longest absorption band of the phosphorescent compound.;

1. An organic compound represented by Formula (G1): wherein: Ar1 represents a substituted or unsubstituted fluorenyl group; Ar2 represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms; A1 represents any one of a substituted or unsubstituted dibenzofuranyl group and a substituted or unsubstituted dibenzothiophenyl group; and a substituent on the substituted fluorenyl group, the substituted aryl group, the substituted dibenzofuranyl group, or the substituted dibenzothiophenyl group is selected from an alkyl group having 1 to 4 carbon atoms and an aryl group having 6 to 13 carbon atoms.
