Abstract

NEW MATERIAL:An ester compound of formula I (R, R' are 1W8C straight-chain alkyl or alkoxy).
EXAMPLE: (2'-Cyano-4'-pentyl)phenyl-4-heptyl benzoate.
USE: Liquid crystal material, or an additive of a liquid crystal composition. The addition of the compound increases the absolute value of the negative dielectric anisotropy of a liquid crystal composition.
PROCESS: The compound I is prepared, as shown in the reaction formulas, by (1) brominating a 4-substituted phenol to a 2-bromo-4-substituted phenol, (2) condensing the product with a 4-substituted benzoic acid chloride, and (3) cyanizing the condensed product.
