The molecules of the title compound, C(34)H(24)N(2)S(4), lie across centres of inversion in the space group P2(1)/n. The spacer unit linking the benzene rings and carbazole units is effectively planar, while the carbazole unit itself is slightly folded. Molecules are linked into sheets by a single C-H···π(arene) hydrogen bond and the hydrogen-bonded sheets are themselves linked into a three-dimensional framework structure by a single π-π stacking interaction.
