Synthesis Of Luminescent Organic Molecules And Its Assembly With CdS Nanoparticles

In this thesis, by using the advantages of supramolecular chemistry in designing functional groups and the efficiency of classic chemistry in bond-forming, functional supramolecular unit was formed by the combination and assembly of inorganic semiconductor CdS nanoparticles and functional organic molecules, which were designed and synthesized. The character of the supramolecular assembly as a monomer is studied to form the organic/inorganic functional polymeric material. This work included the synthesis of functional organic molecules, the preparation of and inorganic semiconductor nanoparticles, the formation of supramolecular assembly and its polymerization.Several photoluminescent functional organic molecules were designed and synthesized, including N,N-dimethyl-N-(naphthalen-1 -ylmethyl)octadecan-1 -aminium chloride (ONDAC), stilbenyldimethylethylammonium bromide (SDAB), 4-methoxyl-stilbenyl-dimethylammonium bromide (MODAB) and N-(4-vinylbenzyl)-N,N-dimethyloctadecan-1-aminium chloride (OVDAC), which could be used in the polymerization.And we discussed the prepared condition of inorganic semiconductor CdS nanoparticles in water. Since the photoluminescence spectrum of ONDAC overlapped partially with the exciton absorbance spectrum of CdS nanoparticles, inorganic semiconductor nanoparticles and functional organic molecules formed functional supramolecular unit, as energy transferring occurred between ONDAC and CdS. The efficiency of energy transfer from functional organic molecule to inorganic nanopartials...
