摘要

本實驗室已成功開發出一系列新型含氟鏈釕金屬的錯合物，並應用在染料敏化太陽能電池上。我們將特有的含氟鏈聯吡啶[4,4’-bis(RfCH2OCH2)-2,2’-bpy]與[4,4’-dicarboxy-2,2’-bpy]接在Ru上，得到[Ru(dcbpy)(4,4’-bis-(RfCH2OCH2)-2,2’-bpy)(NCS)2] (1a-c)、(2a-c),其中Rf分別是HC2F4(a),C3F7(b)與HC4F8(c)。之後產物用管柱分離的方式純化，再以NMR(1H、19F與13C)、FTIR、GC/MS、FAB來分析鑑定。

由於含氟鏈聯吡啶具有極佳的疏水性質，因此我們可藉由氟鏈特性來改善染料敏化太陽能電池原有缺點，以獲得長效穩定性及更高的效率；從相關文獻中可得知不同碳數長鏈的螯合基對於染料會有不同的效率。在論文中將對三種染料與N3、Z907以及N719做個分析比較，並用CV、UV來加以驗證。

A new type of Ru-based solar cell dye complexes has been synthesized successfully and applied to dye-sensitized solar cells. With our particular by designed novel fluorous bipyridine ligand [4,4’-bis(RfCH2OCH2)-2,2’-bipyridine] together with [4,4’-dicarboxy-2,2’-bipyridine], we have achieved the dye complexes [Ru(dcbpy)(4,4’-bis-(RfCH2OCH2)-2,2’-bpy)(NCS)2] (1a-c) where Rf=n-HC2F4(1a), n-C3F7(1b), n-HC4F8(1c), respectively. After purification by column chromatography, the products were analyzed and spectroscopically characterized by multi-nuclei NMR (1H,19F and 13C), FTIR, GC-MS and FAB.

Taking advantage of the fluorous bipyridine ligands; which are hydrophobic and water repellent, we can use the fluorous bipyridine to improve the function of traditional DSSC, with stability and the efficiency. According to early papers, we know the different carbon length of fluorous arms on bpy ligands will lead to diverse effects. In my thesis, I have compared the difference among our own dyes, N3, Z907 and N719, with instrumental analysis such as CV, UV to see to what extent the improvents were made.
