Abstract

NEW MATERIAL:The compound of formulaI(R is 1W10C alkyl or alkoxy).
EXAMPLE: 2-(4-Fluorophenyl)-3c-(4-octyloxyphenyl)-acrylonitrile.
USE: A liquid crystal compound or non-liquid crystal compound having negative dielectric anisotropy. The dielectric anisotropy Δε is about-2.5, and is stable to water, heat, air, etc. The compound is slightly unstable to light, however, there is no practical difficulty by keeping the compound from severe UV irradiation.
PROCESS: The compound of formulaIcan be prepared by adding pyridine to the equimolar mixture of the 4-substituted benzaldehyde of formula II and 4-fluorophenyl acetonitrile of formula III, and heating at 120°C for about 24hr. The compound can be most effectively used by adding to a liquid crystal compound having small negative Δε in an amount of about 10%.
