A new series of amphiphilic heteroleptic ruthenium(II) sensitizers with a fluorous bis-ponytailed bipyridine ancillary ligand, [Ru(H(2)dcbpy)(4,4'-bis(R(f)CH(2)OCH(2))-2,2'-bpy)(NCS)(2)] [where R(f) = HCF(2)CF(2) (CT4), C(3)F(7) (CT7), and HCF(2)CF(2)CF(2)CF(2) (CT8)], have been synthesized and fully characterized by UV/vis, visible emission, NMR, fast atom bombardment mass spectrometry, and cyclic voltammetric studies. Dye-sensitized solar cells (DSCs) based on these dyes exhibit efficiencies comparable with that of the standard cell based on N719. The conversion efficiency of a CT7- or CT8-based DSC is ~9% higher than that of Z907 with a nonfluorous bis-ponytailed bipyridine ancillary ligand. The fluorous chains were found to increase the dye density on TiO(2) and to help to suppress the dye desorption.
一种新型的双亲性杂化钌（II）敏化剂，具有全氟双马尾联吡啶辅助配体[Ru(H(2)dcbpy)(4,4'-双（R(f)CH(2)OCH(2))-2,2'-bpy)(NCS)(2)]，其中 R(f) = HCF(2)CF(2) (CT4)、C(3)F(7) (CT7)和 HCF(2)CF(2)CF(2)CF(2) (CT8)，已通过 UV/vis、可见发射、NMR、快原子轰击质谱和循环伏安研究进行了合成和全面表征。基于这些染料的染料敏化太阳能电池 (DSC) 的效率与基于 N719 的标准电池相当。基于 CT7 或 CT8 的 DSC 的转换效率比具有非全氟双马尾联吡啶辅助配体的 Z907 高出约 9%。发现氟链增加了 TiO(2)上的染料密度，并有助于抑制染料解吸。
