The exploration of novel structures and structural transformation of supramolecular assemblies is of vital importance for their functions and applications. Herein, based on coordination-driven self-assembly, we prepare a neutral truncated tetrahedron and a heteroleptic truncated octahedron, whose structures are unambiguously confirmed by X-ray diffraction analysis. More importantly, the truncated tetrahedron is quantitatively transformed into the truncated octahedron through its fusion with another cationic truncated tetrahedron, as evidenced by fluorescence, mass and NMR spectroscopy. This study not only deepens our understanding of the process of supramolecular fusion but also opens up possibilities for the subsequent preparation of advanced supramolecular assemblies with complex structures and integrated functions.
探索超分子组装体的新型结构及其结构转变对于其功能和应用至关重要。在此，基于配位驱动的自组装，我们制备了一个中性截顶四面体和一个杂配截顶八面体，其结构通过X射线衍射分析得到明确证实。更重要的是，截顶四面体通过与另一个阳离子截顶四面体融合而定量转化为截顶八面体，荧光、质谱和核磁共振光谱证实了这一点。这项研究不仅加深了我们对超分子融合过程的理解，也为后续制备具有复杂结构和集成功能的先进超分子组装体开辟了可能性。
