Basen on the research foundation of laser protection materials for more than twenty years and successful experience for preparation of inorganic hybrid luminesence materials and inganic hybrid low dielectric materials,the molecular design and architecture are made using nano-sized inorganic particles,polyhedral oligomeric silsesquoixane (POSS, Si8O12R8) with a well-defined nano-sized cubeoctameric structure as a building unit. The contronllable preparation of inoganic hybrid functional materials for broad laser protection will be deeply studied by highly efficient, and sensitive "Click Chemistry" method. The enhancement effect and mechanism of POSS nanoparticles on optical properties will be carefully explored by theoretical simulation of molecular geometrical character and arrangement conducted under the Gaussian 03 software suite with B3LYP/6-31G level of theory combining with experimental results of optical properties.The laser protection properties and mechanism of hybrid functional materials will be investigated by time-resolved pump-probe technology and z-scan measurement system with ns and ps ulse width. The retionship between molecular component, molecular structure and optical properties will be summaried. The work of the project will provide a fundation for the design and application of new laser protection materials.
