英文摘要： The inorganic hybrid functional materials, in particular, the synthesis or preparation method of nano-sized inorganic multifunctional hybrid materials are the hot topics of research presently in the field of inorganic functional materials. In the project, the influence of active group structure of molecules on preparation and structural control of POSS monomers will be explored in detail by means of optimizing the reaction conditions. The multifunctional POSS-based inorganic hybrid materials will be prepared through the molecular designs of functional molecules with two-photon absorption or fluorescent probe. Their molecular structure will be characterized by 1H NMR、29Si NMR、FTIR、XRD、element analysis and so on. Their optical properties will be evaluated by cofocus laser system with femtosecond pulse, FL, UV-vis spectral technical. The relationship between molecular structure and their properties will be deeply studied on the basis of investigation of nanometer enhancement and condensed matter emitting enhancement effects. The interaction mechanism among functional groups will be investigated through the experiment combined with theoretical calculation, which hopes to provide researching ways for further development and application of advanced functional materials.
