摘要:
Provided is a novel heterocyclic compound which can be used for a light-emitting element, as a host material of a light-emitting layer in which a light-emitting substance is dispersed. A heterocyclic compound represented by a general formula (G1) is provided. In the formula, A represents any of a substituted or unsubstituted dibenzothiophenyl group, a substituted or unsubstituted dibenzofuranyl group, and a substituted or unsubstituted carbazolyl group, R11 to R19 separately represent any of hydrogen, an alkyl group having 1 to 4 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 14 carbon atoms, and Ar represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms.

摘要:
Provided is a novel heterocyclic compound which has excellent heat resistance and can be used as a host material for a light-emitting substance (a substance emitting fluorescence or a substance emitting phosphorescence). A light-emitting element includes a heterocyclic compound which includes one dibenzo[f,h]quinoxaline ring, one ring having a hole-transport skeleton, and two to eight benzene rings. Note that in the above structure, the molecular weight of the heterocyclic compound is greater than or equal to 564 and less than or equal to 1000.
