摘要

本研究已成功合成出[4,4’-bis-(RfCH2OCH2)-2,2’-bpy)，Rf =HCF2] 、[5,5’-bis-(RfCH2OCH2)-2,2’-bpy)，Rf =HCF2]新型含氟鏈聯吡啶螯合基及[4,4′-dicarboxy(phenylethenyl)-2,2′-bipyridine]具有延伸π共軛之固著螯合基，再以此特有的含短氟鏈聯吡啶合成出一系列敏化染料粗產物，以管柱層析純化，再以NMR(1H、13C、19F)、FTIR、MS-FAB來鑑定。

本研究合成之新型CT系列染料(CT2、5,5’-CT2)根據不同四丁基銨數而有H1TBA3、HTBA、H3TBA1三種型式，然而conjugated-CT系列染料則是藉由固著螯合基延伸的π共軛做為特點，目的在於提升光敏化劑之莫耳吸光係數及可見光的吸光範圍，再以Uv-vis、CV、PL等儀器測得的結果深入探討具不同數目四丁基胺之CT系列染料與conjugated-CT系列染料在光學、電化學及光電轉換效率上有何差異表現。

New fluorous bipyridine ligands of [4,4’-bis-(RfCH2OCH2)-2,2’-bpy), Rf =HCF2] and [5,5’-bis-(RfCH2OCH2)-2,2’-bpy), Rf=HCF2] and extended π-conjugated fixed ligand of [4,4’-dicarboxy(phenylethenyl)-2,2’-bipyridine] have been successfully synthesized and purified in this study. After purification of new synthesized crude dye sensitized products by column chromatography, the products were fully investigated by multi-nuclei NMR (1H, 13C and 19F), FT-IR and MS-FAB respectively.

The three new synthesized types of CT series dyes(abbr. CT2 and 5,5'-CT2) in this study were H1TBA3, HTBA and H3TBA1, which were based on the different numbers of tetrabutylammonium. The results showed that the molar extinction coefficients and visible light spectral range of photosensitizer were increased by using the characteristic of the extended π-conjugation on anchoring ligand in conjugated-CT series dyes. The effects of different tetrabutylammonium CT series dyes and conjugated-CT series dyes on optics, electrochemical and photoelectric conversion efficiency were also discussed in this study.
