Ferrocene-bridged bisporphyrins have been synthesized by the condensation of corresponding dipyrromethane-derived diols with a bisdipyrromethane. Purification of the final compounds has been achieved without chromatography. The specific geometry of these bisporphyrins makes them valuable starting points for building complex molecular and supramolecular structures. In particular it provides a core to which multiple sites of attractive intermolecular interactions can be attached thereby creating compounds predisposed to form complex networks by association. We have studied the structure of bis-1,1â²-(porphyrinyl)ferrocenes by 1H NMR, UV-Vis and electrochemistry. Results have shown that complex dynamic processes occur in these molecules (which may involve conformers, formation of H-aggregates and tautomers) and that they have non-typical electrochemical behaviour.
通过相应的二吡咯烷衍生二醇与双二吡咯烷的缩合,合成了二茂铁桥式双卟啉。最终化合物的纯化无需色谱法。这些双卟啉的特殊几何形状使它们成为构建复杂分子和超分子结构的重要起点。特别是,它提供了一个核心,在这个核心上可以连接多个具有吸引力的分子间相互作用位点,从而创造出易于通过关联形成复杂网络的化合物。我们通过 1H NMR、UV-Vis 和电化学方法研究了双-1,1â²-(卟啉基)二茂铁的结构。结果表明,这些分子中存在复杂的动态过程(可能涉及构象、H-聚集体和同系物的形成),而且它们具有非典型的电化学行为。
