Abstract:
A novel compound which can be used as a material for a light-emitting element is provided. Specifically, a novel compound is provided which can be suitably used as a material for a light-emitting element where a phosphorescent compound enabling high emission efficiency of the light-emitting element is used as a light-emitting substance. In addition, a novel compound is provided which can be easily synthesized and inexpensively manufactured as well as having the above-described characteristics. A compound is provided in which at least one dibenzothiophenyl group or dibenzofuranyl group is directly bonded to a dibenzo[f,h]quinoxaline skeleton.
