(57) [Summary] (Modified) [Constitution] An optically active substance represented by the following formula. Specifically, for example Optical activity-cis-3- (4'-n-decyloxy-4-biphenyl) carboxy-6,6-dimethylcyclohexylcarbonitrile. [Effects] Liquid crystals exhibiting high spontaneous polarization as ferroelectric liquid crystals, no coloring, excellent chemical stability and photostability, and non-ferroelectric liquid crystal compositions exhibiting no liquid crystal properties. When used as an additive for mixing with a substance to form a ferroelectric liquid crystal composition or as a compounding component for a ferroelectric liquid crystal composition, it enhances spontaneous polarization as a composition, increases the helical pitch, and increases the response speed. Will be an improvement. |
