Abstract The intercalation of (±)-2-aminomethylcrowns into α-zirconium phosphate has been investigated by the batch method and followed by X-ray diffractometry. The reaction was dependent on the solvent, and 1-propanol was employed as a solvent. (±)-2-Aminomethyl-12-crown-4 and -15-crown-5 were taken up in two and three stages, respectively, while the uptake process of (±)-2-aminomethyl-18-crown-6 was complicated. Monolayers and bilayers of aminomethylcrowns might be formed when inserted into the interlayer space. 31P CPMAS-NMR and IR spectra of the intercalates suggest that the amino group is protonated by a proton of the phosphate group and/or proton transfer from the phosphate group to the amino group occurred.
