由杂多酸衍生物制备溶致液晶

Synthesis of Lyotropic Liquid Crystals by Heteropoly Compounds Derivatives

液晶是介于液态和晶态之间的一个独立的物质状态，溶致液晶是因溶质在一定浓度范围内分散在溶剂中而呈液晶相．自从１８８８年奥地利植物学家Ｒｅｉｎｉｔｉｚｅｒ和德国物理学家Ｌｅｈｍａｎｎ合作首次发现液晶态以来［１］，迄今为止己发现了五万种以上的液晶性物质．它...

Heteropoly compound, Na 16 P 4W 30 Cu 4(H 2O) 2O 112 \5 n H 2O, has been transferred from water to benzene by phase transfer. After the surface coordinated water molecule was removed and title compound is substituted by pyridine, we get a lyotropic liquid crystal formed by heteropolycompound and small molecule formed by organic basis. It is characterized by polarimicroscope, DSC and heterothermal as well as wide angle X ray diffraction.
