  Synthesis and physical properties of ruthenium bipyridine complexes with TCNQ and TCNE ligands

  摘要：

  [Ru(bpy)(dcbH(2))(TCNQ)Cl] center dot (Ru-TCNQ) and [Ru(bpy)(dcbH(2))(TCNE)Cl] center dot (Ru-TCNE) complexes, where bpy = 2,2'-bipyridine, dcbH(2) = 4,4'-dicarboxy-2,2'-bipyridine. TCNQ = 7,7,8,8-tetracyano-p-quinodimethane, and TCNE = tetracyanoethylene, were synthesized and characterized by spectroscopic and electrochemical techniques. Comparatively to the TCNX ligands (TCNQ and TCNE) free of coordination, the infrared vibrational spectra of the complexes indicate that the coordination to the ruthenium atom occurs through only one nitrile group. Also, the downshift of these bands is indicative of the TCNX reduced form (TCNX center dot-). This conclusion is reinforced by EPR spectra with g = 2.005 and 2.010 for the Ru-TCNQ and Ru-TCNE complexes, respectively. In addition, the structured absorption spectra observed for both complexes indicate that the TCNX moieties are coordinated as anion radicals, (TCNX center dot-). Preliminaries luminescence studies indicate that the Ru-TCNX complexes present emission properties with reasonable lifetimes. The degree of charge transfer for the Ru-TCNQ and Ru-TCNE compounds was evaluated as 0.66 and 0.78, respectively. The Ru-III/II redox potentials (E-ox) for the Ru-TCNQ and Ru-TCNE complexes are observed, respectively, at 0.70 V and 1.30 V versus NHE. The data, all together, suggest that the TCNE species presents a higher charge uptake capability than TCNQ ligand. (C) 2008 Elsevier Ltd. All rights reserved.

  Synthesis and properties of bipyridyl-based dye-sensitizers

  摘要：

  根据4-甲基吡啶的原料，合成了一系列双吡啶衍生物。以双吡啶衍生物作为配体，制备了染料敏化剂Ru(4, 4′-二羧基-2, 2′-双吡啶)2(NCS)2、Ru(2, 2′-双吡啶)(4, 4′-二羧基-2, 2′-双吡啶)(NCS)2和Ru(4, 4′-二甲基-2, 2′-双吡啶)(4, 4′-二羧基-2, 2′-双吡啶)(NCS)2。这些化合物的结构通过红外光谱、元素分析和1H NMR进行了表征，证明它们为目标产物。染料敏化剂的XPS结果显示，双吡啶和–NCS与中心金属钌的配位效果良好。通过TG、UV-Vis和循环伏安法测定染料敏化剂的性能，发现这些染料敏化剂具有优异的热稳定性、宽广的可见光吸收范围，并且与染料敏化太阳能电池的要求匹配良好，能够保证太阳能电池的长期使用。Ru(4, 4′-二羧基-2, 2′-双吡啶)2(NCS)2具有更好的热稳定性和较大的摩尔吸收率，相较于其他两种染料敏化剂，表现出更优秀的吸收效果。

  A new heteroleptic complex, [Ru(dcbH2)(bpy)(9AA)Cl]2+, Ru-9AA (9AA = 9-aminoacridine), was synthesized, characterized and used along with the previously synthesized [Ru(dcbH2)(bpy)(TCNE)Cl], Ru-TCNE (TCNE = tetracyanoethylene), in dye-sensitized solar cells (DSCs). The photoelectrochemical data were evaluated in comparison to the standard [Ru(dcbH2)2(NCS)2] dye, N3. DSCs sensitized by these compounds

  合成了一种新的杂合配合物[Ru（dcbH 2）（bpy）（9AA）Cl] 2 +，Ru-9AA（9AA = 9-氨基amino啶），并与先前合成的[Ru（dcbH 2）一起使用（bpy）（TCNE）Cl]，Ru-TCNE（TCNE =四氰基乙烯），在染料敏化太阳能电池（DSC）中。与标准[Ru（dcbH 2）2（NCS）2 ]染料N3相比，评估了光电化学数据。这些化合物敏化的DSC的Ru-9AA和Ru-TCNE的总效率分别为0.95和2.82％，而N3在相同条件下为5.65％。尽管与标准染料相比，其整体效率较低，但Ru-TCNE络合物仍具有足够的电子注入效率，可以将光有效地转化为电能。
