Hexagonally mesostructured polyoxometalate-based hybrid was prepared by a mild-solution method through the self-assembly of an amphiphilic poly(ethylene oxide) octadecyldimethylammonium (C18NEO12) and a polyanionic silicotungstic acid (HSiW). The composition of the hybrid was characterized through 1H NMR, infrared spectroscopy, mass spectroscopy
