The biogenic amines (dopamine, serotonin, noradrenaline, and adrenaline) were intercalated into layered zirconium phosphates (ZrP). The intercalation reaction into α-ZrP depended on pH of their aqueous solutions. On the other hand, for γ-ZrP the uptake of dopamine and serotonin increased with the increase of their concentration, where as that of noradrenaline and adrenaline depended on pH. Their intercalation compounds were microscopically investigated by solid-state NMR.
