  • Organic compound, light-emitting element, light-emitting device, electronic device, and lighting device
    Patent number: 9496503
    Abstract: 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.
