Herein, we report an artificially assembled interlocked system that features adaptive self‐assembly and induced‐fit transformation properties in the presence of appropriate guest molecules. By careful choice of solvent and guests, a molecular Borromean rings complex based on organometallic half‐sandwich units could be transformed in a stepwise manner to a ring‐in‐ring complex and a monomeric rectangle, leading to a conversion cycle between these structures. This adaptive self‐assembly method was further applied to the construction of a Russian dolls complex, forming another conversion cycle composed of a molecular Borromean rings complex, a Russian dolls complex and a monomeric rectangle. A comprehensive map showing all of the structural transformations between these metallarectangles and interlocked species is drawn up, representing a recoverable and recyclable transformation mechanism.

分子硼烷环，俄罗斯娃娃和环对环复合体之间的自适应自组装和诱导拟合互换

在本文中，我们报告了一种人工组装的互锁系统，该系统在存在适当的客体分子的情况下具有自适应自组装和诱导拟合转换特性。通过仔细选择溶剂和客体，可以将基于有机金属半三明治单元的分子Borromean环配合物逐步转变为环环配合物和单体矩形，从而导致这些结构之间的转化循环。这种自适应的自组装方法被进一步应用到俄罗斯玩偶复合体的构造中，形成了由分子Borromean环复合体，俄罗斯玩偶复合体和单体矩形组成的另一个转化循环。绘制了一张全面的地图，显示了这些金属矩形和互锁物种之间的所有结构转变，
