In the title compound, C22H14S, the r.m.s. deviation from the mean plane of the four-fused-ring naphthothiophene unit is 0.056 Å. The dihedral angle between the naphthothiophene plane and the pendant phenyl ring is 67.24 (6)°. In the crystal, weak C-H and - stacking [minimum centroid-centroid separation = 3.7466 (10) Å] interactions are observed, which together lead to (010) sheets.
