Triazole Derivative, and Light-Emitting Element, Light-Emitting Device, Electronic Device and Lighting Device Using the Triazole Derivative

Objects are to provide the following: a substance that facilitates hole injection and has high triplet excitation energy; a light-emitting element having high emission efficiency using the substance that facilitates hole injection and has high triplet excitation energy; a light-emitting element having low driving voltage; and a light-emitting device, an electronic device, and a lighting device having low power consumption. Provided is a triazole derivative in which a dibenzothiophen-4-yl or dibenzofuran-4-yl group represented by General Formula (G2) is bonded to any one of Ar1 to Ar3 of a triazole derivative represented by General Formula (G1). In the formulas, A represents oxygen or sulfur, Ar1 to Ar3 separately represent a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, and R1 to R7 separately represent hydrogen, an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.

TRIAZOLE DERIVATIVE, HETEROCYCLIC COMPOUND, LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, ELECTRONIC DEVICE AND LIGHTING DEVICE

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.]
