  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.
