Self‐assembly relies on the ability of smaller and discrete entities to spontaneously arrange into more organized systems by means of the structure‐encoded information. Herein, we show that the design of the media can play a role even more important than the chemical design. The media not only determines the self‐assembly pathway at a single‐component level, but in a very narrow solvent composition, a supramolecular homo‐aggregate can be non‐covalently wrapped by a second component that possesses a different crystal lattice. Such a process has been followed in real time by confocal microscopy thanks to the different emission colors of the aggregates formed by two isolated Pt^II complexes. This coating is reversible and controlled by the media composition. Single‐crystal X‐ray diffraction and molecular simulations based on coarse‐grained (CG) models allowed the understanding of the properties displayed by the different aggregates. Such findings could result in a new method to construct hierarchical supramolecular structures.

自组装结构的溶剂驱动超分子包裹

自组装依赖于较小的离散实体通过结构编码的信息自发地排列成更有组织的系统的能力。在此，我们表明介质的设计比化学设计更重要。介质不仅决定单组分水平的自组装途径，而且在非常狭窄的溶剂组成中，超分子均聚物可以被具有不同晶格的第二组分非共价包裹。由于两个分离的Pt ^II形成的聚集体的发射颜色不同，因此共聚焦显微镜实时跟踪了此过程。复合体。该涂层是可逆的，并由介质组成控制。基于粗粒（CG）模型的单晶X射线衍射和分子模拟可以理解不同聚集体显示的性质。这些发现可能会导致一种新的构造分层的超分子结构的方法。
