Abstract:
A novel triarylamine compound having a bipolar property is provided. The triarylamine compound can be used for a hole-injection layer, a hole-transport layer, a light-emitting layer, or an electron-transport layer in a light-emitting element. The triarylamine compound can also be used as a host material with a light-emitting material which emits relatively short-wavelength light, in a structure where the host material and the guest material constitute a light-emitting layer. The triarylamine compound of the present invention is a fluorescent compound and therefore can also be used as a light-emitting substance of a light-emitting layer. A light-emitting element having high emission efficiency is provided. A light-emitting device, an electronic device, or a lighting device having low power consumption is provided.
