英文摘要: The novel functional polymerizable carbon quantum dots (CDs) will be prepared using one-pot in-situ pre-functionalization method established by Young Fund through the design and selection of carbon sources, cement sources and polymerizable groups. The CDs and/or other polymerizable nano and aryleneethynylene materials, with high optical performance, can be introduced and covalently connected to solid hybrid glass host material and appropriate nanomaterials by host-guest precursor molecular copolymerization, physical compatibilizing, fast sol-gel and other method in this project. So, the nanomaterials, organic polymer components and matrix precursor can be mixed in widely/arbitrary ratios and molecular level uniformity without phase separation, leading to high performance, broadband, easy-processed, long-time stable nanohybrid copolymeric gel glasses, coatings, films and devices. It is available to get a new kind of molecular level organicinorganic chemically copolymeric nanocomposite, and accomplish the successful application of broadband-large wavelength laser protection and optical copolymeric materials in practical devices. The relative importance of strcture-property of novel organopolymer -nanomaterial-xerogel glass, pore structure of glass and integration optical limiting protective mechanism will be inves
