Abstract:
Provided is a heterocyclic compound that can be used for a carrier-transport material, a host material, or a light-emitting material in a light-emitting element. The heterocyclic compound has an indolo[3,2,1-jk]carbazole skeleton and a dibenzo[f,h]quinoxaline skeleton which are linked to each other through an arylene group. The wide band gap of the heterocyclic compound allows excitation of a green-emissive phosphorescent material, which contributes to the formation of a highly efficient light-emitting element.
