摘要: PURPOSE:To provide a novel difluorostilbene derivative compound having a low viscosity, excellent in compatibility with other liquid crystals or nonliquid crystals, and useful for chemically stable, especially photostable liquid crystals. CONSTITUTION:A difluorostilbene derivative compound of formula 1 (A , A are trans-1,4-cyclohexylene, 1,4-cyclohexenyle, 1,4-phenylene; X , X are H, F, but at least one of X , X is F; Y , Y are -COO-, -PCP-, -CidenticalC, -CH2CH2-, -CH=CH-, -OCH2-, -CH2O-, single bond; m, n are 0, 1; R , R are alkyl, halogen, cyanol) or formula 2, 2,g, (Z)-1,2-difluoro-1-(2-fluoro-4-methylphenyl)-2-)4-n- propylephenyl)ethylene. The compound of formula I is obtained e.g. from iodotrifluoroethylene of formula 4 through compounds of formulas 5, 6 and 7.
