In the title compound, C28H18F4O2, the central benzene ring makes dihedral angles of 44.27 (6), 56.33 (5) and 77.27 (6)° with the two adjacent fluoro­benzene rings and terminal difluoro-substituted benzene ring, respectively. The dihedral angle between the fluoro­benzene rings is 87.81 (6)°. The meth­oxy and prop-2-en-1-one groups are essentially coplanar with their attached benzene rings, as indicated by their C—O—Car—Car [−0.06 (15)°] and C—C—Car—Car [4.5 (2)°] (ar = aromatic) torsion angles. In the crystal, mol­ecules are linked by C—H⋯F and C—H⋯O hydrogen bonds into sheets lying parallel to the ac plane. The crystal structure also features C—H⋯π inter­actions.
