Abstract: A nanometer amino acid heteropoly charge-transfer complex was synthesized from Keggin structure phosphomolybdic acid (H3PMo12O40·13H2O) and phenylalanine(Phe) by one step solid state reaction at room temperature. The title compound was characterized by means of elemental analysis, IR, XRD, TEM, UV and CV. The results indicate that the sizes of the compound are in the range of 30-40 nm. The heteropoly anion still remains its Keggin structure in the product molecules. A sizeable electron-transfer interaction occurs between phosphomolybdic acid and phenylalanine. The electrochemical behavior of the compound in 1 mol/L H2SO4 shows that three redox waves correspond to three two-electron processes attributing to the reduction of PMo12O403- . Solid state reaction at room temperature is a convenient synthetic method for nanomaterials and may provide a new path to synthesize nanometer amino acid heteropoly complex.
