The title compound, C(28)H(20)F(2)O(2), is a polysubstituted terphenyl derivative bearing a Michael system. The C=C double bond is E configured. In the crystal, C-H⋯O and C-H⋯F contacts connect the mol-ecules, forming undulating sheets that lie perpendicular to the crystallographic a axis. The shortest π-π inter-action [centroid-centroid distance = 3.7163 (7) Å] involves the para-fluoro-phenyl ring in the para position to the Michael system, and its symmetry-generated equivalent.
