Heterocyclic compound, light-emitting element, light-emitting device, electronic device, lighting device, and organic compound

摘要

Provided is a novel heterocyclic compound which can be used in a light-emitting layer of a light-emitting element as a host material in which a light-emitting material is dispersed, i.e., a heterocyclic compound represented by a general formula (G1). Any one of R1 to R10 represents a substituent represented by a general formula (G1-1); another one of R1 to R10 represents hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, or a substituent represented by a general formula (G1-2); and the others separately represent hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, or a substituted or unsubstituted biphenyl group.

1. An organic compound represented by a formula (G1): wherein any one of R1 to R10 represents a substituent represented by a formula (G1-1), another one of R1 to R10 represents hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, or a substituent represented by a formula (G1-2), and the others separately represent hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, or a substituted or unsubstituted biphenyl group: wherein one of R1 and R2 represents hydrogen, wherein α1 in the formula (G1-1) and α2 in the formula (G1-2) separately represent a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenyldiyl group, and wherein Ar1 in the formula (G1-1) and Ar2 in the formula (G1-2) separately represent a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthryl group, or a substituted or unsubstituted triphenylenyl group.
