摘要
以高结晶度制备了层状 (脯氨酸 -N -甲基膦酸 -磷酸氢 )锆 (α-ZPMPP)晶体 (层间距为 1 .5 2 nm ) ,并研究了其常温下对正丁胺的插层性能 ,用元素分析、IR、XRD和 TG-DSC热分析对 α-ZPMPP及其插层复合物进行了表征 .结果表明 ,层状 α-ZPMPP具有形成超分子主 -客体化合物的插层性能 ,正丁胺客体分子在主体底物中形成单分子层 ,并插入 α-ZPMPP中 ,使层间距增大 0 .45 nm,插入的正丁胺可在 1 5 0～ 2 5
Layered zirconium (proline-N-methylphosphonate-phosphate)(α-ZPMPP) was prepared with high crystallization(interlayer distance is 1.52 nm). The intercalation of n-butylamine into α-ZPMPP was also investigated at room temperature. α-ZPMPP and its intercalation complex were characterized by element analysis, IR, XRD and TG-DSC method. It has been found that layered α-ZPMPP possesses different intercalation behavior from α-ZP with the formation of host-guest compound of super-molecule. The interlayer distance of α-ZPMPP-BA was enlarged by 0.45 nm with the intercalation of n-butylamine, the inserted n-butylamine molecules form mono-molecule layer within host matrix and could be removed at 150-250 ℃. The guest molecule n-butylamine forms a mono-molecule layer within host matrix.
