Abstract
It is an object to provide a new substance excellent in electron-transporting property, and a light-emitting element and a light-emitting device using the substance. A quinoxaline derivative represented by the general formula (G1) is provided. In the general formula (G1), each of R1 to R4 represents hydrogen, an alkyl group having 1 to 4 carbon atoms, or an aryl group having 6 to 25 carbon atoms; and each of Ar1 and Ar2 represents an aryl group having 6 to 25 carbon atoms. Such a quinoxaline derivative is excellent in electron-transporting property and very effective as an electron-transporting material in a light-emitting element and the like.
