In the title compound, C28H19BrF2O2, the central benzene ring makes dihedral angles of 62.51 (18), 46.23 (18) and 48.19 (18)° with the bromo-substituted benzene ring and two terminal fluoro-substituted benzene rings, respectively. In the crystal, molecules are linked by C—H⋯F hydrogen bonds into infinite chains along . Weak C—H⋯π and π–π interactions [centroid–centroid distance = 3.683 (2) Å] also occur and short intermolecular F⋯F contacts [2.833 (4) Å] are observed.
