Abstract:
Provided is a novel heterocyclic compound which can be used as a host material for dispersing a light-emitting material in a light-emitting layer of a light-emitting element. Further provided is a light-emitting element which is driven at a low voltage and has high current efficiency. By including the light-emitting element, a light-emitting device, an electronic device, and a lighting device each with reduced power consumption are provided. The light-emitting element contains a compound in which a dibenzo[f,h]quinoline ring and a hole-transport skeleton are bonded through an arylene group. The light-emitting device, the electronic device, and the lighting device each including the light-emitting element are provided. The light-emitting element contains a heterocyclic compound having a structure represented by the following general formula (G1).
