A carbazole derivative represented by the general formula (1) is provided. In the formula, Ar1 represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms which form a ring; α and β independently represent a substituted or unsubstituted arylene group having 6 to 12 carbon atoms which form a ring; R1 represents an alkyl group having 1 to 4 carbon atoms or a substituted or unsubstituted aryl group having 6 to 10 carbon atoms which form a ring; and R11 to R17 and R21 to R28 independently represent hydrogen, an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 10 carbon atoms which form a ring.

Page/Page column 42, (2010/04/23)
To provide a method for producing a wide variety of carbazole derivatives which have a simple and uncomplicated process and in which variations in the yield, purity, etc. of a desired substance which are caused by an aryl group introduced is reduced as much as possible. A method for producing a carbazole derivative represented by General Formula (1) is provided, in which 9-[4-(10-phenyl-9-anthryl)phenyl]-9H-carbazole having an active site at the 3-position of the carbazole skeleton and an aromatic compound having an active site are coupled. In the formula, Ar1 represents an aryl group with 6 to 13 carbon atoms in a ring, and Ar1 may have a substituent.

An object is to provide a light-emitting element having high light-emission efficiency by provision of a novel fluorene derivative as represented by General Formula (G1) below. In the formula, R1 to R8 independently represent any of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, or a substituted or unsubstituted biphenyl group. Further, α1 to α4 independently represent any of a substituted or unsubstituted arylene group having 6 to 12 carbon atoms. Furthermore, Ar1 and Ar2 independently represent any of an aryl group having 6 to 13 carbon atoms in a ring and Ar3 represents an alkyl group having 1 to 6 carbon atoms or a substituted or unsubstituted aryl group having 6 to 12 carbon atoms. J, k, m, and n each independently represent 0 or 1.
