层状(脯氨酸-N-甲基膦酸-磷酸氢)锆的合成及插层性能研究

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1.52nm),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0.45nm,插入的正丁胺可在150～250℃被脱除.

Synthesis and Intercalation Behavior of Layered Zirconium(Proline-N-methylphosphonate-phosphate)

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.
