Abstract

There is provided a chiral compound of the formula ##STR1## where m, 1, and k are integers in the range of 4.ltoreq.m.ltoreq.14, 0.ltoreq.l.ltoreq.7, 0.ltoreq.k.ltoreq.8, respectively, which has the property of being a liquid crystal in itself or can be added to a liquid crystal without any adverse effect on the liquid crystal. The compound induces twisted arrangement when added to a liquid crystal of TN mode or phase change mode, and it increases the spontaneous polarization when added to a SmC* liquid crystal.
