  Nematic Liquid Crystals with a Tetrafluoroethylene Bridge in the Mesogenic Core Structure

  摘要：

  A dramatic increase of the clearing temperatures of liquid crystals based on bis(cyclohcxyl)ethane 1 by 50 to 70 K can be achieved by the perfluorination of the central ethylene link. Conformational analysis indicates that this effect is due to the increased rigidity of the mesogenic core structure and to the suppression of conformers with a bent shape. Materials based on bis(cylohexyl)tetrafluoroethane 2 might play a crucial role as materials for the next generation of active matrix LCDs with reduced power consumption.

  for the synthesis of trans-2,5-disubstituted 1,3-dioxane derivatives, which are important liquid-crystal compounds, was developed. The acetalization reaction between aldehydes and 2-substituted 1,3-propanediols in the presence of acids gave the corresponding 2,5-disubstituted 1,3-dioxane derivatives with high trans selectivity (trans/cis = >96:<4), when the reaction was performed with saturated aqueous

  开发了用于合成重要液晶化合物的反式-2,5-二取代的1,3-二恶烷衍生物的立体选择方法。当存在酸时，醛与2-取代的1,3-丙二醇之间的缩醛化反应可得到相应的2,5-二取代的1,3-二恶烷衍生物，具有较高的反式选择性（反式/顺式=> 96：<4）。该反应用具有高水溶性的无机盐如CaCl 2，LiCl和ZnCl 2的饱和水溶液进行。
