Abstract
NEW MATERIAL:An optically active compound shown by formula I (group shown by formula II is group shown by formula III or formula IV; -X- is -CO-O- or -O-; R1 is 4-18C alkyl; R2 is optically active alkyl). EXAMPLE:6-(4-n-Octyloxyphenyl)pyridine-3-carboxylic acid 4'-[(S)-1-methylhep tyloxycarbonyl]phenyl ester. USE:One component for a liquid crystal composition, having especially ferroelectricity, excellent mutual solubility with other liquid crystal compounds, providing chiral smectic C liquid crystal having excellent weather resistance and high-speed response, useful as optical electronics elements such as optical printer head, optical Fourier transform element and light valve. PREPARATION:A compound shown by formula VII is treated with an excess amount of SOCl2 for several hours under reflux to form an acid chloride shown by VIII, which is reacted with a compound shown IV at room temperature or under heating for several hours to give a compound shown by formula I.
