The molecule of the title compound, C17H10F4O, is roughly planar, with a dihedral angle of 5.59 (14)° between the two phenyl rings. The molecule has an E conformation with respect to the olefinic bonds. In the crystal, molecules are connected through C—H⋯O hydrogen bonds and there is slipped π–π stacking [centroid–centroid distance = 3.7983 (18), slippage =1.309 ;Å] between symmetry-related benzene rings.
The title compound is a derivative of the biologically active compound curcumin [systematic name (1E,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione].
