摘要：
It is an object to provide a novel bipolar organic compound. In particular, it is an object to provide a bipolar organic compound excellent in thermal stability. Further, it is another object to provide a bipolar organic compound which is electrochemically stable. A quinoxaline derivative represented by a general formula (1) is provided. Further, since the quinoxaline derivative represented by the general formula (1) is bipolar, the use of the quinoxaline derivative of the present invention allows fabrication of a light-emitting element and a light-emitting device with a low driving voltage and low power consumption. Furthermore, a light-emitting element with high luminous efficiency can be obtained.
