已经制备了具有各种含氟极性端基的液晶化合物（参见下式1，其中Z = S <$CHF 2、S <$CF 3、SO <$CHF 2、SO <$CF 3、SO 2 <$CHF 2、SO 2 <$CF 3、SO 2 F、OCH 2 CF 3、CO <$OCH 2 CF 3、CO <$CF 3、CO <$CF 2 Cl、CO <$CF 2 H、CO <$CF 2 <$CH 3、CO <$CF 2 <$C3 H 7）。这些化合物的合成概述在这里和它们的物理性质（相变，介电各向异性，双折射，粘度）进行了讨论。
Abstract Liquid crystalline compounds with various polar terminal groups containing fluorine have been prepared (see below formula 1 with Z = S‒CHF2, S‒CF3, SO‒CHF2, SO‒CF3, SO2‒CHF2, SO2‒CF3, SO2F, OCH2CF3, CO‒OCH2CF3, CO‒CF3, CO‒CF2Cl, CO‒CF2H, CO‒CF2‒CH3, CO‒CF2‒C3H7). The synthesis of these compounds is outlined here and their physical properties (phase transitions, dielectric anisotropy, birefringence, viscosity) are discussed.
