Abstract

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.

Partial Text

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]. For the biological activity and applications of curcumin, see: Aggarwal et al. (2007 ▶); Kamat et al. (2009 ▶); Liang et al. (2009 ▶); Pan et al. (1999 ▶); Sharma et al. (2007 ▶); Zhao et al.
