In the title compound, C29H22F2O2S, the central benzene ring makes dihedral angles of 45.83 (7), 38.90 (7) and 55.50 (7)° with the two fluoro-substituted benzene rings and the methyl­sulfanyl-substituted benzene ring, respectively. In the crystal, C—H⋯O contacts connect the mol­ecules into layers lying perpendicular to the c axis. In addition, π–π stacking inter­actions between one of the fluoro­phenyl groups [centroid–centroid distances = 3.681 (1) and 3.818 (1) Å] are observed.
