摘要 含1,1 二氟乙撑基和乙炔基的C2桥键类液晶是非常重要的TN、STN、TFT用液晶材料。通过对文献方法进行简化和改进后合成了1,1 二氟 1,2 二芳基取代乙烷和1,2 二芳基取代乙炔类液晶,总产率分别达到26%和39%。产物结构用IR、1HNMR做了鉴定。 Liquid crystal containing C2 bridge of 1,1difluoroethane or ethyne group are synthesized by an improved method with overall yield 26% and 39%, which are very important materials used in TN, STN, TFT liquid crystal composition. The structures of the compounds are confirmed by IR,1H NMR.
