Abstract: An organic compound has a benzonaphthofuran skeleton and is represented by General Formula (G1). In General Formula (G1), A represents a pyrene skeleton. In the case where the pyrene skeleton has a substituent, the substituent is a diarylamino group including two substituted or unsubstituted aryl groups each having 6 to 13 carbon atoms, a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, an alkyl group having 1 to 7 carbon atoms, a substituted or unsubstituted monocyclic saturated hydrocarbon group having 3 to 20 carbon atoms, or a substituted or unsubstituted polycyclic saturated hydrocarbon group having 7 to 10 carbon atoms. The two aryl groups of the diarylamino group may be the same or different. In X1 represented by General Formula (G1-1), one of R6 and R7 is bonded to N in General Formula (G1), and the other of R6 and R7 represents an alkyl group having 1 to 7 carbon atoms, a substituted or unsubstituted monocyclic saturated hydrocarbon group having 3 to 20 carbon atoms, or a substituted or unsubstituted polycyclic saturated hydrocarbon group having 7 to 10 carbon atoms.

Abstract: A light-emitting element with high emission efficiency and high reliability is provided.
The light-emitting element includes a host material and a guest material in a light-emitting layer. The host material has a function of converting triplet excitation energy into light emission and the guest material emits fluorescence. The molecular structure of the guest material is a structure including a luminophore and protecting groups, and five or more protecting groups are included in one molecule of the guest material. The introduction of the protecting groups into the molecule inhibits energy transfer of triplet excitation energy by the Dexter mechanism from the host material to the guest material. As the protecting group, an alkyl group or a branched-chain alkyl group is used.
