The liquid phase synthesis of aromatic amines four kinds of organisms with Keggin structure phosphorus molybdenum heteropoly acid synthesis four charge-transfer -type hybrid materials , and four hybrid material system characterization , as well as the nature of light and color , the results as follows: 1 element analysis by ICP-AES , AAS , and TG determine the molecular structure of the resulting hybrid material ; IR, XRD and cyclic voltammetry (CV) curves show that the resulting hybrid material remains the molybdenum phosphate Keggin structural features . 2 ESR , and UV-vis results show that charge transfer occurs between the aromatic amine with the Keggin structure molybdenum phosphate , resulting in the reduction of phosphate of the organic electron donor oxide and molybdenum , to generate a mixed-valence organic - inorganic charge transfer type hybrid materials . 3 uses diffusion - prepared single crystal to give the DMA-PMo12 monocrystalline , fine structure analysis of single crystal , the results show that the aromatic amine with heteropoly acid by hydrogen bonds between the supramolecular compound is formed on the two - dimensional planar structure . 4 were studied hybrid materials in solution as well as the nature of light and color of the polymer film , and the results show that the existence of the state of the hybrid materials , its light color phenomenon . Both in solution as well as a polymer film having excellent light color , different light color phenomenon and in solution having a bleaching , can be used as a rub -type storage material ; medium , since the polymer in the film , The environment is more complex hybrid material does not fade , and can be used as a permanent storage materials .
