Abstract
NEW MATERIAL:3-n-Butoxy-6-(trans-4'-alkylcyclohexanecarboxy)-phthalonitrile of formula (R is 1W10C alkyl).
USE: A liquid crystal substance having extremely large negative dielectric anisotropy, and low melting point. It can be used as a displaying substance of a display element which is based on guest-host effect, DAP effect, or DSM effect, and can be driven at a low voltage.
PROCESS: Reaction of mono-n-butyl ether of 2,3-dicyano-p-hydroquinone with trans- 4-alkylcyclohexanecarboxylic acid halide in a basic solvent affords the compound of the formula.
