Supramolecular Intercalation Assemble of Crystal Mixed Zirconium Phosphate

Layered and pillared material are a kind of multifunctional material which were developed in recent years. Much attention has been paid to this kind of material for its application in ion-exchange, catalyst, solid state proton conductivity, nonlinear optics and physic. A lot of literature have reported the intercalation behavior of a-zirconium phosphate (abbreviated as a-ZrP), different guest molecules inserted into α-ZrP have been studied in detail, those guest molecules include amine, alcohol, amino acid, protein, enzyme, coornadiate compound and coronal compound. The intercalation guest is restricted by their size and basicity. Although a lot of researches have been done to α-zirconium phosphate intercalation, the intercalation behavior of zirconium phosphate-phosphonate has been seldom dealt with.

Crystal zirconium phosphate-phosphonate has the stability and regularity of interlayer floor of inorganic a-zirconium phosphate, they still have the designability of the organic group in the interlayer and adjustment of the ratio of organic and inorganic phosphorus acid. They are a kind of potential smart material, we can process molecule design and optimize filtration according to the requirement of goal reaction. We can prepare special ion-exchange, catalyst, catalyst supporter, nonlinear optics compound, solid state proton conductivity and the intercalation complex precusor by introducing different active organic group or active center into the choice and stable framework of inorganic α- zirconium phosphate.

Our research has proved that the study of intercalation behavior of zirconium phosphonate-phosphate drives the development layered and pillared material, pointing a new direct for selecting good host matrix, and pushed the research of zirconium phosphonate-phosphate into a new area. Taking advantage of the abundant and diversity of molecule design, we can synthesis special layered and pillared materials by introducing different organic functional group into the interlayer space of α-ZrP.
