NEW MATERIAL:A liquid crystal compound shown by formula I (R is ≤20C alkyl; R*is optically active functional group containing asymmetric carbon atom; n is 0 or 1 and n=0 means absense of corresponding benzene uncleus). n EXAMPLE: [4-Oxycarbonyl-S]-2-methylbutylphenyl.4-decanoyloxybenz-oate. n USE: Useful as a component for liquid crystal composition, stable to water, light, etc., showing SC* phase in a wide temperature range and being blended with a compound usually showing no SC* phase and several liquid crystal compounds to contrive to reduce the temperature range to show SC@{50F/30} phase. Being used alone and effective as a display element utilizing light switching phenomena of ferroelectric liquid crystal. n PREPARATION: A compound shown by formula II is condensed with a compound shown by formula III to give a compound shown by formula I. n COPYRIGHT: (C)1987,JPO&Japio |
