Abstract:
To provide a novel heterocyclic compound capable of being used as a host material in which a light-emitting substance is dispersed. To provide a light-emitting element having a long lifetime. A heterocyclic compound in which a dibenzo[f,h]quinoxalinyl group and a benzo[b]naphtho[1,2-d]furanyl group are bonded through an arylene group having 6 to 13 carbon atoms. The dibenzo[f,h]quinoxalinyl group, the benzo[b]naphtho[1,2-d]furanyl group, and the arylene group separately are unsubstituted or have, as a substituent, an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 13 carbon atoms.
