英文摘要： Synthesize several functional cyclodextrin, crown ether and calixarene molecular shuttles driven by light and pH et al. Prepare spherical gold nanoparticles (GNPs)and their hybrids modificated by molecular shuttles or their functional component molecules via S-Au covalent bonds. Controllably adjust the morphological assembly of the hybrid GNPs via the supramolecular interaction of the organic molecules modificated on its surface. Investigate the stumili-response properties of the organic functional GNP hybrids. Prepare aqueous CTAB protected gold nanorods (GNRs) solution and their organic-soluable hybrids modificated by molecular shuttles or their functional component molecules via S-Au covalent bonds. Study the typical Plasma Absorption change of the hybrid GNRs comparing with the CTAB protected GNRs. Controllably adjust the morphological assembly of the hybrid GNRs by the supramolecular interaction between their surfactant functional molecules. Explore the stumili-response properties of the organic functional GNR hybrids. Employ the supramolecular interaction of the surfactant molecule components on the GNPs and GNRs to investigate the controllable and complicated morphological assembly involving GNP and GNR hybrids and their photophysical and photochemical properties.
