摘要： An optically active 2-fluoro-1-alkanol compound represented by the formula (Ia): ##STR1## wherein R is an alkyl group having 1-16 carbon atoms, and C* is an asymmetric carbon atom; and an optically active compound derived from the fluoroalkanol and represented by the formula (Ib): ##STR2## wherein R and C* are the same as above, m is 1 or 2, n is 0 or 1, and A is a releasable substituent. Because of the fluorine atom directly attached to an asymmetric carbon atom, these compounds are particularly effective in increasing a spontaneous polarization, improving a electric field responsive characteristic of a liquid crystal composition, and controlling the liquid crystal state.

摘要： A liquid crystal composition, comprising a main chain-type mesomorphic polymer and a mesomorphic monomer and showing a smectic phase including a plurality of molecular layers, wherein a linkage of a covalent bond is present between adjacent molecular layers among the plurality molecular layers. Because of the presence of the covalent bond linkage between the molecular layers, the elastic energy of the liquid crystal per se relating to the elastic energy between the smectic liquid crystal molecular layers can be controlled to provide a uniform alignment. The mesomorphic polymer preferably has a structure represented by the following formula (1): ##STR1## wherein A denotes a terminal flexible chain group, M denotes a mesogen group, F denotes a spacer flexible chain group, x is 0 or 1, B denotes an ester bond group, ether bond group, thioester bond group, dimethylsiloxane bond group or thioether bond group, and y is 1-200.
