Abstract

NEW MATERIAL:A 4-alkyl-4'-(4"-cyanobenzolyloxy)-3'-cyanobiphenyl I (R is 1W 8C straight chain alkyl).
EXAMPLE: 4-Octyl-4'-(4"-cyanobenzoyloxy)-3'-cyanobiphenyl.
USE: An additive for a liquid crystal composition for the double frequency display method. It gives a high and positive dielectric anisotropy at the lower frequency range and a high absolute value and negative dielectric anisotropy at the higher frequency range, and therefore it lowers the driving voltage and the consumption of electric power.
PROCESS: p-Cyanobenzoyl chloride III is esterified with a 4-alkyl-4'-hydroxy-3-bromobiphenyl II in the presence of pyridine to give the compound IV. The compound IV is reacted with copper (I) cyanide in DMF to give the compound I.
