Abstract:
To provide a novel organic compound having a bipolar property. To reduce power consumption of a light-emitting element, a light-emitting device, and an electronic device. The organic compound has a fluorene skeleton and a structure in which an electron-accepting unit and a hole-accepting unit are bonded through carbon at the 9-position of the fluorene skeleton. The organic compound has a bipolar property and a large band gap. The use of the organic compound makes it possible to reduce power consumption of a light-emitting element, a light-emitting device, and an electronic device.
