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.
