The title compound, C(26)H(18)F(2)O(4), is a naphthalene derivative in which the two aroyl groups at the 1- and 8-positions (peri positions) are anti to each other. There is an appreciable difference in the dihedral angles between the naphthalene ring system and the two benzene rings [66.88 (7)° and 88.09 (6)°]. In the crystal, weak C-H⋯O inter-actions involving one of the carbonyl groups and an aromatic C-H group ortho to the F atom seem to stabilize the packing of the mol-ecules.
