【摘要】 以新的路线合成了两类文题化合物共七个液晶单体，合成了催化剂（１，３－双－（二苯基膦基）丙烷－二氯化镍）和光活性中间体（Ｓ）－２－甲基丁基苯酚，获得了较高的产率及纯度。经元素分析、质谱和红外光谱分析确证了化合物的分子结构，测定了其液晶相态。进行了配方尝试，得到了对温度变化敏锐的热变色液晶材料，具有较好的应用前景。更多还原

【Abstract】 Seven chiral theamotropic liquid crystals were synthesized with a series of new methods.Ni（dppp）Cl₂,an important catalyst in Grignard Reaction,a11d p-（S）-2-methyl-butyl phenyl,an important inteamediate,were synthesized with a higher yield and purity. Their structures were determined with 1R,MS and element analysis.By using these compounds,a series of theamotropic color liquid crystal materials were obtained.更多还原
