  3. In this paper we studied the intercalation behavior of a new host matrix of x = l of zirconium proline - n - mtthyl phosphonate - phosphate ( a - zpmpp ), we successfully introduced butylamine heptylamine decanylamine ethanolamine diethylenetriamine ( 2e3a ) triethyleneteriamine ( 3e4a ) and tetrathyleneoctamine ( 4e5a ) guest molecules into a - zpmpp interlayer space. the intercalation complex were characterized by ir spectrum x - ray diffraction and tg - dsc thermal analysis, it has been found that a - zpmpp possess different intercalation behavior from a - zrp. because of the bulk of proline group, it affected the amount of guest molecule, mono - alkylamine form mono - molecule layer in the interlayer space, butylamine, decanylamine and ethanolamine form mono - layer and the carbon chain form 90 degree ordered assembly with the zirconium floor of a - zpmpp, every host molecule absorbed 0. 5 guest molecule

    本文報道首次以x ? l的層狀(脯氨酸十一甲基磷酸一磷酸氫)鉛( a zpmpp )為主體底物,成功地將客體分子:胺、慶胺、癸胺、乙醇胺、二乙三股、三乙四胺、四乙五股插入層狀化合物a zpmpp的層間,通過紅外光譜( ir ) 、 x射線衍射( xrd ) 、熱重分析( tg dsc )等手段對插層復合物進行結構表徵,結果表明: x ? l的層狀(脯氨酸件一甲基磷酸一磷酸氫)鉛具有不同於無機磷酸結的插層性能,由於層間脯氨酸基團的體積較大,影響客體分子進入的數量,胺分子在層板間取單層排列。
