Abstract

NEW MATERIAL:The compound of formula I [R is 1-7C n-alkyl; R' is 1-4C n-alkyl; configuration of the cyclohexane ring is trans(equatorial-equatorial)]. EXAMPLE:The compound of formula V. USE:An electro-optical display material. It is a nematic liquid crystal compound having weak negative dielectric anisotropy, small anisotropy of refractive index (DELTAn) and low viscosity. It can be used as a dynamic light-scattering display cell or field-effect display cell by mixing with other compound. PREPARATION:The objective compound of formula I can be produced by reacting a compound of formula II with ethylene glycol in an inert solvent in the presence of a catalyst such as p-toluene-sulfonic acid, reducing the resultant compound of formula III with AlCl3 and lithium aluminum halide in anhydrous ether to obtain a compound of formula IV, reacting the compound with sodium hydride in a solvent and then reacting with an alkyl halide.
