摘要： Novel chiral smectic ester compounds suitable for liquid crystal compositions are expressed by the formula
wherein R represents an alkyl group of 1 to 18 carbon atoms; R * represents an optically active alkyl group of 4 to 18 carbon atoms: X represents a single bond, -0- , -CO-O- , -0-CO- or -O-CO-O-- ; A represents -CO-0- or -0-CO- ; and m and n each is 1 or 2.

摘要： Chiral smectic compounds with a high response rate and superior as a ferroelectric liquid crystalline material are expressed by the formula
(wherein X represents -CH 2 -, -O- or-CO-; n represents 0. 1 or 2: when X reoresents -CH 2 -. Y recresents R-. R-CO-. ROCO-,
wherein R represents an alkyl group having 1 to 18 carbon atoms, and when X represents -0- or-CO-, Y represents R; and * represents a symbol indicating an optically active carbon atom) and can be used in chiral smectic mixtures.
