The nonlinear optical material is the international research hotspot in the field of microelectronics devices and life science. This project is based on the theoretical calculation. In the first we will design and synthesize the special functional organic ligands, then according to the principle of coordination chemistry, supramolecular chemistry. Then by adding the suitable reductant, and the heteropoly anions are modified to construct composite materials , in order to explore their third order nonlinear optical function and develop molecular engineering, crystal engineering. In project implementation, we choose the relations between nonlinear optical effect and microscopic structures of organic-inorganic hybrid polyoxometalates as the main line, by using time-resolved spectra and tunable ultrafast laser spectroscopy, combined with quantum chemistry calculation, study of nonlinear optical effect, more acid matrix composites interface transmission mechanism, the energy transfer mechanism, and organic primitives and the function of the composite effect between metal-oxygen clusters and organic components, optimize the reaction conditions, structure and properties of materials, to achieve synergies between the organic and inorganic part of the material, variable light bands and low cost manufacturing key technologies. The three-dimensional optical storage materials, photoelectric conversion, ion recognition and application of biological development will be explored. Our research will provide the new ideas and methods for the development of new two-photon absorption materials and organic modification organic-inorganic hybrid materials based on the heteropoly anions.
