摘　　要：制备了晶态层状(甘氨酸N,N双亚甲基膦酸磷酸氢)锆(αZGDMPP),层间距为1.52nm,研究了αZGDMPP对正丁胺的插层性能。用元素分析、X射线衍射、红外光谱、固体核磁共振谱13CCP/MASNMR和热分析测试技术对αZGDMPP和插层复合物进行了表征。结果表明,αZGDMPP具有不同于αZP的形成主客化合物的插层性能,正丁胺的插入使αZGDMPP的层间距增大1.02nm,插入的正丁胺呈双分子层排列,碳链与层板夹角约为55°,在150～250℃从层板中脱出。Layered crystalline zirconium (glycine-N,N-dimethylenephosphonate-phosphate)(α-ZGDMPP) was prepared(interlayer distance is 1.52 nm). The intercalation complex of n-butylamine into α-ZGDMPP was (also) investigated. α-ZGDMPP and its intercalation complex were characterized by elemental analysis, XRD, IR, ^(13)C CP/MAS NMR and TG methods. The results show that the intercalation behavior of layered (α-ZGDMPP) is different from that of α-ZP with the formation of host-guest compound. The interlayer distance of α-ZGDMPP is enlarged 1.02 nm, n-butylamine molecules intercalated form bilayers and the carbon chains (incline) at rough 55° to α-ZGDMPP layers, the intercalated n-butylamine is lost in the temperature range of (150~)250 ℃.
