In the title compound, C28H19F3O2, the central benzene ring forms dihedral angles of 48.69 (6), 60.93 (6) and 42.06 (6)° with the fluorobenzene rings. In the crystal, intermolecular C—H⋯O and C—H⋯F hydrogen bonds link the molecules, forming an undulating two-dimensional network parallel to the bc plane. C—H⋯π interactions further consolidate the crystal packing.
