1-cyclohexyl-2-cyclohexylbiphenylethane derivative

Abstract

Abstract NEW MATERIAL:1-[trans(e,e)-4'-n-alkylcyclohexyl]-2,4''-[trans(e,e)-4'''-n- alkylcyclohexylbiphenyl]ethane of formulaI(R1, R2 are 1-7C straight-chain alkyl). USE:Nematic liquid crystal: ut is characterized by its high temperature of nematic-isotropic transition and low viscosity and it shows high chemical stability to resist water, light and other factors and opaque white color, thus being suitably used in field effect mode cells, dynamic scattering mode cells and guest-host type cells. PREPARATION:Anhydrous aluminum trichloride and a compound of formula III are made to act on a compound of formula II in carbon disulfide or nitrobenzene and the produce is made to react with hydrazine and potassium hydroxide in diethylene glycol to produce the compound of formulaI.
