Highly-functionalized inorganic material, zirconium phosphate (Zrp) was prepared to study structural difference between intercalated mono-alkylamine and di-alkylamine. Because the density of cation exchange sites (CEC) on the layer surface of synthetic Zrp was much higher than that of other smectites such as montmorillonite (MMT), intercalated alkylamine had higher packing density and adopted more stretched trans-conformations, thus its characteristic structures (i.e., monolayer, interdigitated layer, or bilayer) were understood by monitoring its dspacing. As intercalated amount of mono-alkylamine whose only one endfunctional amine was tethered onto Zrp surface increased, its interlayer structure was changed from monolayer to interdigitated layer, and finally to bilayer. On the other hand, intercalated di-alkylamine with two endfunctional amine on its both chain end, was formed into only monolayer, which indicate that its two endfuctional amines were tethered onto both sides of Zrp layer preventing forming bilayer formation.
