Abstract
NEW MATERIAL:A carboxylic ester of tetrafluorophenol shown by the formulaI[Z is a group shown by the formula II (R is 1W15C alkyl) or formula III].
EXAMPLE: Trans-4-(trans-4'-ethylcyclohexyl)cyclohexanecarboxylic acid 2,3,5,6- tetrafluorophenyl ester.
USE: A display element for liquid crystal. The titled compound is a smetic liquid crystal compound having a Δε of about +0.5, has a wide temperature range of smetic liquid crystal, low viscosity, and good compatibility with other liquid crystal composition, so it operates in a wide temperature range from lowWto high temperature.
PROCESS: A carboxylic acid derivative shown by the formula ZCOOH is reacted with thionyl chloride, to give an acid chloride shown by the formula ZCOCL, which is reacted with tetrafluorophenol, to give a compound shown by the formulaI.
