The invention relates to a fused ring organic compound and a mixture and organic electronic device comprising the same. The fused ring organic compound shown in a general formula (I) has excellent electron transport properties and stability, material synthesis is simple, and when a synthesized material is applied to a device host material, the luminous efficiency and stability of the device can beimproved, and the production cost of the device can be reduced. In addition, a co-host can be formed through cooperation of the fused ring organic compound with another host with a hole transport property or a bipolar property, the electroluminescent efficiency and the service life of the device can be improved further.

Page/Page column 256-257, (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.
