Abstract:
A substance having high excitation energy is provided. In particular, a substance having high triplet excitation energy is provided. Further, a light-emitting element, a light-emitting device, and an electronic device each having high emission efficiency and low driving voltage are provided. A triazole derivative to which an amino group is bonded is provided. In addition, a light-emitting element, a light-emitting device, and an electronic device each including the triazole derivative to which the amino group is bonded are provided.
