Abstract
NEW MATERIAL:A liquid crystal compound of formulaI(R is 2W8C alkyl or alkenyl; R' is 2W8C alkyl or alkenyl).
EXAMPLE: 4'-n-Butyryloxyphenyl-trans-4-n-propylcyclohexanecarboxylate.
USE: A material for a liquid crystal display element having the following properties: (1) A wide nematic temperature range loated on a high temperature side. (2) No part for cutting off ultraviolet light is required since the compound is colorless, transparent and chemically stable. (3) Low viscosity and rapid response. (4) Slight change in threshold voltage with temperature and improved multiplex driving property.
PROCESS: A trans-4-alkylcyclohexanecarboxylic acid of formula II is reacted with thionyl chloride to give a compound of formula III, which is then reacted with an alkylcarbonyl chloride of formula IV to afford a compound of formula V. The resultant compound of formula V is then reacted with the compound of formula III in the presence of pyridine to give the compound of formulaI.
