Abstract:
To provide a novel compound which can be used as a host material in which a light-emitting substance is dispersed. To provide a light-emitting element having a long lifetime. A compound represented by General Formula (G0). In the formula, A1 represents a dibenzo[f,h]quinoxalinyl group, A2 represents a benzo[b]naphtho[2,3-d]furanyl group, and Ar represents an arylene group having 6 to 25 carbon atoms. The dibenzo[f,h]quinoxalinyl group, the benzo[b]naphtho[2,3-d]furanyl group, and the arylene group are separately unsubstituted or substituted by any one of an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, and an aryl group having 6 to 13 carbon atoms. A1-Ar-A2 (G0)
