Intercalation of dendritic polyamines by α- and γ-zirconium phosphates

Tridentate polyamines, N(CH2CH2NH2)(3) and N(RNH2)(3) (R = CH2CH2CONHCH2CH2), react with both alpha- and gamma- zirconium phosphates to give an intercalated phase in which the amine molecules are fully loaded as an interdigitating monolayer with their flatted molecular planes highly titles relative to the inorganic layers. On the other hand, although hexadentate polyamine, N(RN(RNH2)(2))(3), forms a more expanded intercalate from its dilute solution, the longer chain amine can not be intercalated from its concentrated solution, due to the entanglement of dissolved molecules.
