| Summary: | 碩士 === 國立臺灣科技大學 === 材料科學與工程系 === 102 === The organic conjugated polymer has been rapidly developed in the past decade, and the application of conjugated polymer to the chemosensor has attracted considerable attention. Fluorescence conjugated polymer chemosensors for metal ions sensing which containing bipyridine units and phenylenevinylene moieties were prepared in this thesis. Nitrogen-based ligands such as 2-2’-bipyridine can effectively coordinate a variety of metal ions. The polymer conformation changed due to the coordination with metal ions, and the optical properties present something different subsequently. Addition of heavy metal ions to the fluorescent polymer solution and dipping the polymer films to heavy metal ions solution generated a different extent of fluorescent quenching and absorbance red-shift, and these could be applied to the detection of the presence of transition metal in our environment.
