摘要
以水滑石Mg4Al2(OH)12CO3.4H2O为前体,采用返混沉淀方法进行插层组装制备了L-(-)-酒石酸、L-(-)-天冬氨酸、L-(-)-苹果酸柱撑水滑石(LDHs),用X射线衍射、红外光谱及差热分析表征了超分子结构手性层柱材料的结构,结果表明,3种手性酸根阴离子可以插入水滑石的层间完全取代CO32-,得到结晶度高、晶相单一且手性酸根阴离子在层间有序排列的超分子结构手性层柱材料。
L-（-）-Tartaric acids, L-（-）-Aspartic acids and L-（-）-Malic acias were intercatated into me tayereu double hydroxides （LDHs）by a new synthesis method. The structures of supramolecular chrial materials were characterized by XRD,FTIR and DTA. The results show that the initial interlayer carbonate ions can be completely replaced by the chosen chiral acid anions and the high crystallized supramolecular chrial materials were obtained.
