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。
Seven chiral theamotropic liquid crystals were synthesized with a series of new methods.Ni(dppp)Cl_2,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.
