Carbazole Derivative, Light-Emitting Element Material and Organic Semiconductor Material

A carbazole derivative represented by a general formula (G1),

• wherein Ar1 represents any one of a phenylene group, a naphthylene group, and a biphenylene group, and
• wherein Ar2 represents a group that has 14 to 30 carbon atoms and includes a condensed tricyclic ring, a condensed tetracyclic ring, a condensed pentacyclic ring, a condensed hexacyclic ring, or a condensed heptacyclic ring,
• wherein R0 represents a group represented by a general formula (g1),
• wherein R8 represents any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, an aryl group having 6 to 15 carbon atoms, and a group represented by a general formula (g2),
• wherein a substitution site of R0 is a carbon atom represented by either α or β,
• wherein a substitution site of R8 is a carbon atom represented by either γ or δ,
• wherein n is either 0 or 1,
• wherein Ar1 has no substituent or a first substituent, and the first substituent is an alkyl group having 1 to 4 carbon atoms,
• wherein Ar2 has no substituent or a second substituent, and the second substituent is any of an alkyl group having 1 to 4 carbon atoms and an aryl group having 6 to 15 carbon atoms,
• wherein X1 represents oxygen or sulfur, and R1 to R7 individually represent any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 15 carbon atoms, and
• wherein X2 represents oxygen or sulfur, and R9 to R15 individually represent any one of hydrogen, an aryl group having 6 to 15 carbon atoms, and an alkyl group having 1 to 4 carbon atoms.
