This invention relates to a chiral non-racemic composition corresponding to the general formula: R1-Ar-O-CH2-C * HX-C * HY-CH2-O-R2, wherein R1 represents a tail group composed of two to sixteen atoms of carbon; Ar represents a nucleus of achiral ferroelectric liquid crystals (FLC) having at least two nuclei; * indicates a chiral carbon; X and Y represent halogens; and R2 represents one to 10 carbon atoms. The segment -O-CH2-C * HX-C * HY-CH2-O- comprises the chiral proximal segment of the chiral tail; the proximal segment is selected from the 2R, 3R-dihalo and 2S, 3S-dihalo enantiomers. R2 represents the distal segment of the chiral tail. |
