INTERCALATION OF ORGANIC MOLELECULES INTO LAYERED PHOSPHATES

CORRELATION BETWEEN STRUCTUE AND FUNCTION

抄録

Precise investigation of intercalation compounds of layered phosphates by solid state NMR could explore the microscopic picture of intercalation phenomena. By ³¹P solid state NMR experiment, type of layered phosphate and existence of various phosphates, H₂PO₄^-, HPO₄^2-, and PO₄^3- groups, can be distinguished. The microscopic picture of diethylenetriamine-intercalated α-zirconium phosphate, and its mechanism can be obtained by ¹³C and ³¹P solid state NMR. Furthermore, the adsorption of carboxylic acids by diethylenetriamine-intercalated α-zirconium phosphate and the exchange of methylene blue with butylamine in butylamine-intercalated α-zirconium phosphate can be clarified microscopically.
