A substance that facilitates hole injection and has high triplet excitation energy is provided. A light-emitting element having high efficiency or a long lifetime is provided. A light-emitting element driven with a low voltage is provided. Provided is a light-emitting element including triazolo[4,3-f]phenanthridine derivative (G0) or a triazolo[3,4-a]isoquinoline derivative (G4). Provided are triazolo[4,3-f]phenanthridine(G0) and triazolo[3,4-a]isoquinoline(G4) derivatives, which are novel and can be used for the light-emitting element. [wherein E, Ar, A, and X have the designation cited in claims.]
A triazole derivative represented by General Formula (G0) is provided. In the General formula (G0), A represents a substituted or unsubstituted carbazolyl group, a substituted or unsubstituted dibenzothiophenyl group, or a substituted or unsubstituted dibenzofuranyl group, E represents substituted or unsubstituted triazolo [4,3 f]phenanthridine or substituted or unsubstituted triazolo [3,4-α]isoquinoline, and Ar represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms.
