Abstract: Provided is a compound having an indolo[3,2,1-jk]carbazole skeleton and a heterocyclic skeleton which are bonded to each other through an arylene group. The heterocyclic skeleton contains an imidazole skeleton, a pyrazine skeleton, a pyrimidine skeleton, a triazole skeleton, or a condensed heteroaromatic ring including any of these heterocycles. The high carrier-transport property and the large band gap of the compound allows the used as a host material of a phosphorescent dopant, leading to the formation of a green to blue emissive phosphorescent light-emitting element having high emission efficiency, low driving voltage, and reduced power consumption.
