Three-dimensional superstructures of unique self-assemblies generated by exploring the conformational flexibility of various dipyrromethenes through creation of hydrogen-bonds with metal-halide anions are reported and the conformational diversity is thoroughly described in the solid and solution states by X-ray diffraction analysis and variable temperature NMR spectroscopy. The tetrahedral or octahedral structures of their precursors, various metal-dipyrromethene complexes, are also reported, based on the crystallographic data. STM images of the self-assemblies observed on graphite surfaces present interesting arrangements and appear as tubular bunches.
探索通过与金属卤化物阴离子形成氢键而具有构象灵活性的各种二吡咯亚甲基,生成了独特的自组装三维超结构,并通过X射线衍射分析和变温NMR光谱法详细描述了其在固态和溶液状态下的构象多样性。基于晶体学数据,还报道了它们前体的四面体或八面体结构,这些前体是各种金属二吡咯亚甲烯配合物。在石墨表面观察到的自组装结构的STM图像呈现出有趣的排列,并呈现出管束状的外观。
