摘要

本研究主要以雙氟鏈輔助螯合基合成一系列釕金屬錯合物，[(Bu4N) Ru(dcbpyH) (4,4'-bis(RfCH2OCH2)-2,2'-bpy) (NCS)2] [其中Rf = HC2F4 (CT4-HTBA)、 n-C3F7 (CT7-HTBA)與HC4F8 (CT8-HTBA)]以及[Ru(dcbpyH2)(4,4'-bis(RfCH2OCH2)-2,2'-bpy)(NCS)2] [Rf = HC6F12]，合成之光敏劑使用NMR(1H、13C與19F)、FTIR、MS-FAB、UV-Vis與循環伏安法(Cyclic Voltammetry studies)等來分析鑑定其結構及性質。
　　CT系列含氟鏈兩性光敏劑在光電轉換效率表現上優於染料N719及Z907。雖無π共軛系統來增加吸光能力，但疏水的碳氟鏈不僅對於TiO2薄膜有較佳的吸附密度，並且也提昇染料的穩定性。
另外，在AM 1.5 光源測試條件下，CT4-HTBA、CT7-HTBA、CT8-HTBA及CT12-HTBA在電池元件之光電轉換效率分別為7.33%、6.68%、7.13%及5.97%。在相同元件組裝與量測條件下，N719及Z907之光電轉換效率分別為7.08%及6.36%。

A new series of amphiphilic heteroleptic ruthenium(II) sensitizer with a fluorous bis-ponytailed bipyridine ancillary ligand, [(Bu4N)Ru(dcbpyH)(4,4'-bis(RfCH2OCH2)-2,2'-bpy)(NCS)2] [where Rf = HC2F4 (CT4-HTBA), n-C3F7 (CT7-HTBA) and HC4F8 (CT8-HTBA)] and [Ru(dcbpyH2)(4,4'-bis(RfCH2OCH2)-2,2'-bpy)(NCS)2] [where Rf = HC6F12] have been synthesized and fully characterized by NMR, FTIR, MS-FAB, UV- Vis and cyclic voltammetric studies.
Instead of using extending π-conjugated system, our simple fluorous amphiphilic dyes, CT series exhibit efficiencies comparable with that of homoleptic standard N719 dye, and better than that of Z907. The hydrophobic fluorous chains in these new dyes not only lead to higher dye density on TiO2 film, but also suppress the dye leaching.
Under the illumination of AM1.5 stimulated light, the photon-to-current conversion efficiency of CT4-HTBA, CT7-HTBA, CT8-HTBA, and CT12-HTBA sensitized cells was 7.33%, 6.68% , 7.13%, and 5.97% respectively. Under the same device fabrication and measuring procedures, the conversion efficiency of N719 and Z907-sensitized cell were 7.08% and 6.36% respectively.
