A new method for designing nanomodified inorganic–organic materials is proposed, and one example of synthesizing mesostructured vanadate–poly(ethylene glycol) composite is demonstrated. Commercially available poly(ethylene glycol) was changed in its terminal hydroxy group(s) to ammonium head group by two-step sequential tosylation/nucleophilic substitution in order to enable connection with the vanadate framework component. Self-organization of vanadate and the new organic template was successfully processed in the aqueous mixture to precipitate as a composite by adding sodium chloride. We discuss not only the design of a mesostructured material, but also the reasonable treatment for obtaining it from the mixture by the same technique as the volume shrinkage of an amphiphilic block copolymer in water.
