  摘要：

  双核rh（I）与1,2-双（4,4'-甲基-[[2,2']联吡啶基）-乙烷和1,2-双（4,4'-甲基-[2,2']的配合物作为桥联配体的双吡啶基）-十二烷及其单核类似物已经合成并通过其光谱学和电化学性质进行了表征。烷基接头不影响第一还原电势和发光性质以及TEOA的发射态的还原猝灭。通过对单金属配合物和双金属配合物的光催化CO 2还原的详细比较，发现了对活性的巨大有益作用，这取决于中心的接近程度。在高稀释度下，CO 2中的整体动力学单核络合物的光还原显然是单金属的。如果根据OER（一种电子还原物种）的寿命来调节中心的接近度，则光催化活性将大大提高，显示出清晰的双金属机理。在双核rh络合物中，可以实现简便的自由配位位点生成和有效的两个电子转移的双核相互作用。

  A series of polypyridyl-ruthenium(II) and -iridium(III) complexes that contain labile chlorido ligands, [M(tpy)Cl}2μ-bbn}]2/4+ Cl-Mbbn; where M = Ru or Ir; tpy = 2,2′:6′,2′′-terpyridine; and bbn = bis[4(4′-methyl-2,2′-bipyridyl)]-1,n-alkane (n = 7, 12 or 16)} have been synthesised and their potential as antimicrobial agents examined. The minimum inhibitory concentrations (MIC) and minimum bactericidal concentrations (MBC) of the series of metal complexes against four strains of bacteria – Gram positive Staphylococcus aureus (S. aureus) and methicillin-resistant S. aureus (MRSA), and Gram negative Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa) – have been determined. All the ruthenium complexes were highly active and bactericidal. In particular, the Cl-Rubb12 complex showed excellent activity against all bacterial cell lines with MIC values of 1 μg mL−1 against the Gram positive bacteria and 2 and 8 μg mL−1 against E. coli and P. aeruginosa, respectively. The corresponding iridium(III) complexes also showed significant antimicrobial activity in terms of MIC values; however and surprisingly, the iridium complexes were bacteriostatic rather than bactericidal. The inert iridium(III) complex, [Ir(phen)2}2μ-bb12}]6+ where phen = 1,10-phenanthroline) exhibited no antimicrobial activity, suggesting that it could not cross the bacterial membrane. The mononuclear model complex, [Ir(tpy)(Me2bpy)Cl]Cl2 (where Me2bpy = 4,4′-dimethyl-2,2′-bipyridine), was found to aquate very rapidly, with the pKa of the iridium-bound water in the corresponding aqua complex determined to be 6.0. This suggests the dinuclear complexes [Ir(tpy)Cl}2μ-bbn}]4+ aquate and deprotonate rapidly and enter the bacterial cells as 4+ charged hydroxo species.

  Covalently linked bipyridyl ligands (L-L) with alkyl linkages varying from (-CH 2 -) 2 to (-CH 2 -) 12 were used to prepare ruthenium oxo dimers of the form [(bpy) (H 2 O)RuO(L-L)Ru(H 2 O) (bpy)] 4+ . The bridging alkyl linkage increases the stability of these oxo dimers by maintaining the relative proximity of the two ruthenium centers even when the oxo bridge is cleaved.

  The paper reports the synthesis and characterisation of a series of flexible di-bidentate bridging ligands in which two 4-methyl-2,2′-bipyridine groups are linked at the 4′-position by polymethylene (bbn), linear polyether (bbOn) or linear alkylamine (bbNn) chains of varying length (n). The enantiomers (ΔΔ/ΛΛ) of the rac forms of the ruthenium(II) dinuclear complexes incorporating these ligands – i.e. [Ru(phen)2}2(μ-BL)]4+ (phen = 1,10-phenanthroline; BL = bbn, bbOn or bbNn) – have been isolated by reaction of Δ- or Λ-[Ru(phen)2(py)2]2+ (py = pyridine) with the respective bridging ligands. Mononuclear species - in which only one of the bidentate moieties of the bridging ligand is coordinated – have also been isolated, as well as trinuclear and tetranuclear species involving the bb7 bridge. Fluorescence displacement studies of the DNA-binding of the dinuclear complexes containing the bbOn and bbNn bridges generally revealed a lower affinity than their bbn analogues for an oligonucleotide containing a single bulge site; the mononuclear complexes showed a lower affinity - and the trinuclear and tetranuclear complexes a higher affinity – than the dinuclear species, revealing an interesting interplay of lipophilicity, electrostatics and size in the complex/nucleic acid interaction. Cytotoxicity studies of these complexes against a murine leukaemia cell line revealed that the presence of the polyether or polyamine links in the chain lowered the cytotoxicity compared with their polymethylene analogues, and that the bb7-bridged trinuclear and tetranuclear complexes showed considerably enhanced cytotoxicity compared with the dinuclear Rubb7 analogue.

  该论文报道了一系列柔性二齿桥连配体的合成和表征，其中两个4-甲基-2,2'-联吡啶基团通过聚亚甲基（bbn）、线性聚醚（bbOn）在4'位连接或不同长度 (n) 的线性烷基胺 (bbNn) 链。包含这些配体的钌(II)双核配合物的外消旋形式的对映体 (ΔΔ/ΛΛ) – 即 [Ru(phen)2}2(μ-BL)]4+ (phen = 1,10-菲咯啉； BL = bbn、bbOn 或 bbNn) – 通过 Δ- 或 Λ-[Ru(phen)2(py)2]2+ (py = 吡啶) 与各自的桥接配体反应分离。单核物种（其中仅桥配体的二齿部分之一被配位）以及涉及 bb7 桥的三核和四核物种也已被分离出来。含有 bbOn 和 bbNn 桥的双核复合物的 DNA 结合的荧光置换研究通常表明，与含有单个凸出位点的寡核苷酸相比，它们的 bbn 类似物具有较低的亲和力；与双核物质相比，单核复合物表现出较低的亲和力，而三核和四核复合物则表现出更高的亲和力，揭示了复合物/核酸相互作用中亲脂性、静电和大小之间有趣的相互作用。这些复合物针对小鼠白血病细胞系的细胞毒性研究表明，与聚亚甲基类似物相比，链中聚醚或多胺连接的存在降低了细胞毒性，并且与双核 Rubb7 类似物。
