  Liquid crystalline compounds for use in liquid crystal composition, suitably in admixture with other compounds, have the formula : wherein R1 represents a C1-C12 alkyl group in which one or two non-adjacent -CH2- groups, other than the terminal -CH2- group, may be replaced by an oxygen atom or a -CO-, -OCO-, -COO- or -CH=CH- group ; X and Z each represent an H, F or Cℓ atom ; Y represents a C1-C4 perfluoroalkyl group or a C1-C4 perfluoroalkyloxy group in which one or two F atoms may be replaced by H atoms; one of A, B and C represents a cyclohexane ring and the others of A, B and C can be selected from covalent bonds or cyclohexane or benzene rings, which rings may be substituted by F or Cf ; and f, m and n are the same or are different and each is 0 or 1, provided that when m=0, f=0.

  用于液晶组合物的液晶化合物，可与其他化合物混合使用，其结构式为......： 其中 R1 代表 C1-C12 烷基，其中一个或两个不相邻的-CH2-基团（末端的-CH2-基团除外）可被氧原子或-CO-、-OCO-、-COO-或-CH=CH-基团取代；X 和 Z 分别代表 H、F 或 Cℓ 原子；Y 代表 C1-C4 全氟烷基或 C1-C4 全氟烷氧基，其中一个或两个 F 原子可被 H 原子取代；A、B 和 C 中的一个代表环己烷环，A、B 和 C 中的其他可选自共价键或环己烷环或苯环，这些环可被 F 或 Cf 取代；以及 f、m 和 n 相同或不同，且各为 0 或 1，但当 m=0 时，f=0。
