Page/Page column 150-151, (2009/07/17)
To provide a light-emitting element having high luminous efficiency and to provide a light-emitting device and an electronic device which consumes low power and is driven at low voltage, a carbazole derivative represented by the general formula (1) is provided. In the formula, α1, α2, α3, and α4 each represent an arylene group having less than or equal to 13 carbon atoms; Ar1 and Ar2 each represent an aryl group having less than or equal to 13 carbon atoms; R1 represents any of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, and a substituted or unsubstituted biphenyl group; and R2represents any of an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, and a substituted or unsubstituted biphenyl group. In addition, l, m, and n are each independenly 0 or 1.
