  可溶性铂（II）炔基配合物的光谱学和光氧化还原性质

  摘要：

  摘要合成了六种具有叔π-受体配体2,6-（N-（n-（正己基）苯并咪唑-2'-基）吡啶和不同的乙炔基苯配体的铂（II）配合物，并通过光学方法对其进行了研究。吸收，发光和时间分辨发射光谱。这些络合物显示出与先前研究的具有2,2'：6'，2''-叔吡啶配体的类似物相似的光物理和电化学性质。发光带最大值的能量是与乙炔基苯配体相连的化学取代基的性质的函数，根据能隙定律，发光强度和寿命与发光波长相关。其中一些配合物的发射激发态以接近扩散控制极限的效率被还原性淬灭，即使对于中等电子给体（如吩噻嗪或三苯胺）也是如此。具有与乙炔基苯配体连接的二甲胺取代基的配合物表现出强烈依赖于胺的质子化状态的光物理性质。具有二乙炔基取代的an吨桥联配体的二聚体配合物显示的吸收和发射行为与这项工作中研究的某些单体铂配合物的吸收和发射行为基本相同。短的Pt（II）–Pt（II）接触仅在前体复合物的晶体结构中观察到。新配合物的

  Self-Assembled Bilayers as an Anchoring Strategy: Catalysts, Chromophores, and Chromophore-Catalyst Assemblies

  摘要：

  Anchoring strategies for immobilization of molecular catalysts, chromophores, and chromophore-catalyst assemblies on electrode surfaces play an important role in solar energy conversion devices such as dye sensitized solar cells and dye-sensitized photoelectrosynthesis cells. They are also important in interfacial studies with surface-bound molecules including electron-transfer dynamics and mechanistic studies related to small molecule activation catalysis. Significant progress has been made in this area, but many challenges remain in terms of stability, synthetic complexity, and versatility. We report here a new anchoring strategy based on self assembled bilayers. This strategy takes advantage of noncovalent interactions between long alkyl chains chemically bound to a metal-oxide electrode surface and long alkyl chains on the molecule being anchored. The new methodology is applicable to the heterogenization of both catalysts and chromophores as well as to the in situ "synthesis" of chromophore-catalyst assemblies on the electrode surface.

  Three heteroleptic pyridine/benzimidazole-based ruthenium sensitizers, [Ru(L1)(dcbpyH(2))NCS](SCN) (Y1, L1 = 2,6-bis(1-benzylbenzimidazol-2-yl)-pyridine, dcbpyH(2) = 4,4'-dicarboxylic acid-2,2'-bipyridine), [Ru(L2)(dcbpyH(2))NCS](SCN) (Y2, L2 = 2,6-bis(1-ethylbenzimidazol-2-yl)-pyridine), and [Ru(L3)(dcbpyH(2))NCS](SCN) (Y3, L3 = 2,6-bis(1-hexylbenzimidazol-2-yl)-pyridine) are synthesized and applied to dye-sensitized solar cells (DSSCs). The power-conversion efficiency of dye Y3 is higher than those of dyes Y1 and Y2, due to the modification of the auxochromic ligand with a hexyl moiety. The origins of the performance diversity in these devices have been studied with respect to power-conversion efficiency by UV-Vis absorption and emission spectra, cyclic voltammograms (CV), electrochemical impedance spectroscopy (EIS), intensity modulated photocurrent spectroscopy (IMPS), intensity modulated photovoltage spectroscopy (IMVS), and density functional theory (DFT) studies. The better solar-cell performance of Y3 compared to Y1 and Y2 was believed to derive from the enhanced electron lifetimes. (C) 2012 Elsevier B. V. All rights reserved.
