In the title compound, C20H16O4S, the thiophene ring makes dihedral angles of 72.9 (2) and 60.5 (2)°, respectively, with the dimethoxy benzene and phenyl rings. In the crystal, C—H
O hydrogen bonds link the molecules into a C(9) chain along the b axis. The S and C atoms of the thiophene ring are disordered over two sets of sites [site occupancies = 0.675 (3) and 0.325 (3)]. A short intermolecular SO contact [3.084 (2) Å] is observed in the crystal structure, which also features C—Hπ interactions.

In the title compound, C24H16O2, the naphthalene ring system makes dihedral angles of 78.5 (6) and 65.5 (7)° with the terminal and central benzene rings, respectively. The dihedral angle between the benzene rings is 74.5 (8)°. In the crystal, neighbouring molecules are interlinked through two C—Hπ interactions, which construct a two-dimensional supramolecular framework extending infinitely along (010).
