  • Structural Properties of Ruthenium Biimidazole Complexes Determining the Stability of their Supramolecular Aggregates
    作者:Nils Rockstroh、Katrin Peuntinger、Helmar Görls、Dirk M Guldi、Frank W. Heinemann、Bernhard Schäfer、Sven Rau

    The results of a detailed investigation of the influence of substituents in a variety of ruthenium biimidazole-type complexes [Ru(R-bpy)2(R´-bi(bz)imH2)]2+ (R = H, tBu; R´ = H,Me; bi(bz)imH2 = 2,2´-bi(benz)imidazole) on selected structural and photophysical properties is reported. The photophysical properties are only marginally influenced by the substituents at the bipyridine and the biimidazole core. All complexes show intense absorptions in the visible range of the spectrum with maxima around 475 nm, and emission from the formed excited state occurs at wavelengths between 650 and 670 nm. The comparison of structural properties determined by X-ray analysis within a series of related complexes shows that the Ru-N bond lengths to the coordinated bipyridines are not significantly influenced by the substituents, but slight differences in the Ru-N bond lengths to the biimidazole-type ligands can be detected. The reactions between ruthenium complexes containing different biimidazole-type ligands with the sulfate dianion, however, show a strong correlation between the substituents at the biimidazole core and the solubility of the product. The bibenzimidazolecontaining complexes precipitate from aqueous solution whereas the ruthenium complex containing unsubstituted biimidazole stays in solution. The solid-state structure of one example of the sulfatecontaining products (2b) shows that strong hydrogen bonds between the secondary amine function of the bibenzimidazole and the oxygen functionalities of the sulfate contribute to this unexpected behavior.

    报告了对各种钌双咪唑型配合物[Ru(R-bpy)2(R´-bi(bz)imH2)]2+(R = H,tBu;R´ = H,Me;bi(bz)imH2 = 2,2´-双(苯并)咪唑)中取代基对选定结构和光物理性质的影响进行了详细调查。光物理性质受到苯基吡啶和双咪唑核心上的取代基的影响很小。所有配合物在可见光谱范围内显示出强烈的吸收,最大吸收波长约为475纳米,形成激发态的发射波长在650至670纳米之间。通过X射线分析确定的一系列相关配合物的结构性质比较表明,与配位的吡啶相比,钌-氮键长受取代基影响不大,但可以检测到与双咪唑型配体的钌-氮键长之间的轻微差异。然而,含有不同双咪唑型配体的钌配合物与硫酸根二阴离子之间的反应显示出双咪唑核心上的取代基与产物的溶解性之间存在强相关性。含有双苯并咪唑的配合物从水溶液中沉淀,而含有未取代的双咪唑的钌配合物保持在溶液中。硫酸根产物的一个示例(2b)的固态结构显示,双苯并咪唑的次氨基功能与硫酸根的氧官能团之间的强氢键有助于这种意外行为。
