摘要
(a)新型糖精鹽類用於醯化催化反應之回收與再利用 本論文成功的合成與純化DMAP與糖精結合之鹽類，意外地發現DMAP鹽類及其類似結構之鹽類，可用於催化醇的酯化反應，其轉化產率及反應時間與現有之期刊論文相比較，整體反應效率提高約三十倍，且反應無須添加溶劑與鹼基，在室溫下即可進行。本論文改善以往觸媒不易回收的缺點，利用非極性溶劑如正己烷或甲苯，可溶解醯化產物而觸媒不溶之特性，經由離心即可簡易回收觸媒，符合現代綠色科學的回收再利用之概念。 (b)高效率含氟鏈具不同四丁基胺之釕金屬錯合物用於敏化太陽能電池之研究 本論文將特有的含氟鏈聯吡啶與[4,4’-dicarboxy-2,2’-bpy]接在Ru 上，得到敏化染料粗產物，以管柱層析純化，再用NMR(1H、19F 與13C)、FTIR、FAB來鑑定。 我們合成的CT系列染料根據含的四丁基胺數不同而有H1TBA3及H3TBA1兩種型式，染料分子具不同數目四丁基胺在光電轉化效率上有不同的表現。利用UV-vis、CV等儀器測得結果與N719作比較，探討不同四丁基胺的染料在光學、電化學及光電轉換效率的表現。

(a)The New Saccharin Salts Used in the Catalytic Acylation Reaction and Recycling We had successfully synthesized and purified the salt made of DMAP and saccharin. It’s surprising to discover that DMAP-salt and the other salts have the similar structure, and they can used in the catalytic esterification reaction of the alcohol. Conversion yield percentage and reaction time compared with the literature data, the overall efficiency of the reaction about 30 times. However, the reaction without adding solvents and bases can be carried out at room temperature. This discovery is based on the crystallization for series of saccharin and saccharin’s compounds. In the thesis, we improve the disadvantages of catalysts recycling. The non-polar solvents can soluble the acylation product, but catalyst can’t. We use catalyst insoluble characteristics through the centrifuge can easily recycle catalysts. Furthermore, the recycle-easy catalysts are based on concept of modern green technology. (b)High Efficient Bis(fluoro-ponytailed) Bipyridine Ruthenium complexes containing Tetrabutylammonium for Dye-Sensitized Solar Cells We used particular by designed bis(fluoro-ponytailed) bipyridine binding with rethenium. After purification of crude dye by column chromatography, the product was analyzed and spectroscopically characterized by multi-nuclei NMR (1H, 19F and 13C), FTIR and FAB. We synthesis of the CT series of dyes containing different tetrabutylammonium numbers had H1TBA3 and H3TBA1 two types. Dye molecules with different tetrabutylammonium numbers of photoelectric conversion efficiency. UV-vis, CV and other instruments measured results compared with the N719. We study the different tetrabutylammonium numbers of the dye in the optical, electrochemical and photoelectric conversion efficiency.
