The synthesis of a new series of photoluminescent compounds, namely 5,8-diaryl quinoxaline derivatives (aryl = phenyl, 4-fluorophenyl, 4-methoxyphenyl, and 4-cyanophenyl), was achieved by a direct Suzuki cross-coupling reaction with the employment of a NCP-pincer palladacycle. The electrochemical and photophysical properties of these compounds were also investigated. Four new 4,8-diaryl-2,1,3-benzothiadiazoles

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 R
1
to R
4
represents hydrogen, an alkyl group having 1 to 4 carbon atoms, or an aryl group having 6 to 25 carbon atoms; and each of Ar
1
and Ar
2
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.
