Patent ID: 8614334

Claim:
A carbazole compound represented by General Formula (G1): wherein R 1 represents an alkyl group having 1 to 12 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthrylgroup, a substituted or unsubstituted triphenylenyl group, or a substituent represented by General Formula (G1-1); wherein R 2 represents hydrogen, an alkyl group having 1 to 12 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, or a substituent represented by General Formula (G1-2); wherein α 3 represents either a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenyldiyl group, wherein Ar 3 represents a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthryl group, or a substituted or unsubstituted triphenylenyl group, wherein Ar 1 represents an alkyl group having 1 to 12 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthryl group, or a substituted or unsubstituted triphenylenyl group, wherein α 1 represents either a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenyldiyl group, wherein n represents 0 or 1, wherein Ar 2 represents an alkyl group having 1 to 12 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenylgroup, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted phenanthryl group, or a substituted or unsubstituted triphenylenyl group, wherein α 2 represents either a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenyldiyl group, wherein in the case where R 1 , R 2 , and Ar 3 have substituents, the subtituents are separately an alkyl group having 1 to 12 carbon atoms, an unsubstituted phenyl group, an unsubstituted biphenyl group, an unsubstituted naphthyl group, an unsubstituted phenanthryl group, or an unsubstituted triphenyl group, and wherein in the case where α 3 has a substituent, the substituent of α 3 is an alkyl group having 1 to 12 carbon atoms.
