Liquid crystal compounds

The invention discloses optically active liquid crystal compounds represented by the formulas [I], [II] and [III]: STR1 wherein R1 and R2 each represents an alkyl group of 4-18 carbon atoms, X represents O, COO or a single bond, and (A), (B), (C), (D) and (E) each represents STR2 in which l represents a halogen. The invention further discloses optically active liquid crystal compounds which are able to exhibit tristable states, represented by the formulas [IV], [V] and [VI]: STR3 wherein R1 ' and R2 ' each represents a straight chain alkyl group of 5-16 carbon atoms, X' represents O or COO and (A), (B), (C), (D) and (E), and l each has the same meaning as above.

Liquid crystal compound

Liquid crystal compound of the formula STR1 wherein R1 and R2 each is a C1-18 alkyl group or an aralkyl group, R' is a haloalkyl group, X is --0--, --CO--, --COO-- or direct bond, Y is --COO--, --OCO-- or --CH2 O--, (A) and (B) each is STR2 and p and l each is zero or one.

Liquid-crystalline copolymer

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.
