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
