In the title compound, C15H10F2O, the molecule exists in an E conformation with respect to the C=C bond [1.3382 (16) A ̊]. The dihedral angle between the fluoro-substituted benzene rings is 6.80 (6) and the whole molecule is roughly planar(r.m.s. deviation for the non-H atoms = 0.069 A ̊). In the crystal, molecules are linked by C—H...F and C—H...O interactions into sheets lying parallel to the bc plane
