Abstract: The title compound, C27H29F3O5, is a liquid crystal (LC) and exhibits enanti­otropic SmA phase transitions. In the crystal, the dihedral angle between the 2H-chromene ring system and the benzene ring is 62.97 (2)°. The three F atoms of the -CF3 group are disordered over two sets of sites with occupancy factors 0.71 (4):0.29 (4). In the crystal, pairs of C-H...O hydrogen bonds form inversion dimers and generate R22(10) rings. The structure also features C-H...F and C-H...[pi] inter­actions along [100] and [010], respectively.
