A liquid-crystalline copolymer having a long helical pitch, the liquid-crystalline copolymer comprises the copolymerization product of; (a) at least one liquid-crystalline epoxy compound having a helical structure and (b) at least one liquid-crystalline epoxy compound having a helical structure opposite in twining direction of helix to the helical structure of the liquid--crystalline epoxy compound (a) or (c) at least one non-liquid-crystalline epoxy compound.
Synthesis and Mesomorphic Properties of Ferroelectric Liquid Crystals with a Fluorinated Asymmetric Frame (1)

A fluoroalkane derivative represented by the formula: STR1 wherein R denotes an alkyl group having 1-16 carbon atoms, C* denotes an asymmetric carbon atom, R1 denotes an alkyl or alkoxy group having 1-16 carbon atoms; STR2 respectively denote a phenylene group STR3 a cyclohexylene group STR4 or a pyrimidinylene group STR5 p is 0 or 1, q is 0 or 1 when p is 1, r is 0 or 1; and l, m and n are respectively 0 or a positive integer satisfying the relationship of l+m+n≥1. The fluoroalkane derivative has a fluorine atom providing a large dipole moment and directly connected to an asymmetric carbon atom, so that it provides a high speed responsive characteristic through an increased spontaneous polarization when contained in a liquid crystal composition, especially a ferroelectric liquid crystal composition.
