ABSTRACT:
The present invention provides a novel organic compound having excellent heat resistance. By using the novel organic compound, a light-emitting device and an electronic device having excellent heat resistance can be provided. A quinoxaline derivative represented by the general formula (1) is provided. Since the quinoxaline derivative represented by the general formula (1) has excellent heat resistance, when it is used for a light-emitting element, a light-emitting device using the light-emitting element also have excellent heat resistance. Further, electronic devices having excellent heat resistance can be provided.
