摘要：
Optically active compound for use in liquid crystal compositios provided with suitable characteristics, have the formula:
in which R¹ and R² are each a C₁-C₂₀ alkyl group or C₁-C₂₀ alkoxy group or a hydrogen atom; ℓ , m and n are each 0 or 1; X is a fluorine, chlorine or bromine atom or a cyano group, and the group
are each independently a group
(in which Y is hydrogen or halogen atom or a cyano group).
