摘要 |
A novel organic compound which can be used as a host material for a phosphorescent compound is provided. A light-emitting element containing the organic compound is provided. A light-emitting device, an electronic device, and a lighting device each of which includes the light-emitting element are provided. In the light-emitting element including a light-emitting layer interposed between a pair of electrodes, the light-emitting layer contains at least an organic compound and a phosphorescent compound. In the organic compound, a dibenzo[f,h]quinoxaline skeleton and an amino group having two substituents are bonded to each other through an arylene group. The substituents are separately an aryl group or a heteroaryl group.
