Abstract

A novel compound is provided. Alight-emitting device having high emission efficiency and a long lifetime is also provided. An organic compound is represented by General Formula (G2), in which a benzo[a]anthracene skeleton is bonded to the 2-position of an anthracene skeleton. In General Formula (G2), R1 to R3, R5 to R12, and R21 to R29 each independently represent any one of hydrogen, an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms in a ring. Another embodiment of the present invention is a light-emitting device including the compound.

First claim

wherein the light-emitting layer comprises a host material and a guest material,
wherein the host material comprises a benzo[a]anthracene skeleton and a substituted anthracene skeleton,
wherein the benzo[a]anthracene skeleton is bonded to a 2-position of the anthracene skeleton,
wherein a 9-position of the anthracene skeleton and a 10-position of the anthracene skeleton each independently comprise a substituted or unsubstituted aryl group having 6 to 13 carbon atoms,
wherein the guest material comprises a luminophore, and
wherein the luminophore comprises a benzofuran skeleton.

11. A light-emitting apparatus comprising:
