  Novel Liquid Crystalline Four Ring Chain Difluoromethyleneoxy Compounds for Quicker Response LC Mixtures

  摘要：

  A series of chemically stable novel liquid crystalline four ring chain compounds (1a-1c) having a difluoromethyleneoxy (CF(2)O) linkage moiety have been designed and prepared, and their properties have been thoroughly investigated. The novel compounds intrinsically possess much higher positive Delta epsilon (>32) and Delta n (>0.190), relatively low viscosity, wider nematic phase temperature ranges and significantly higher clearing temperatures in comparison to the analogous three ring chain CF(2)O compound (2) that is currently applied in almost all the latest TN-TFT monitors, notebook PCs and IPS-TVs.
