Abstract: 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.

Key words: Zirconium(proline-N-methylphosphonate-phosphate), n-Butylamine, Intercalation complex, Host-guest compound, Mono-molecule layer
