In the crystal structure of the title compound, C 20 H 14 S, the thiophene rings are disordered; such a flip‐type disorder is typical for simple, monosubstituted thiophene derivatives. Two planar fragments, the thiophene and the anthracene units, are almost perpendicular in order to relieve the H⋯H steric strains. The crystal packing is determined by van der Waals interactions, π–π stacking between the anthracene fragments, and some weak C—H⋯S and C—H⋯π short directional contacts.
