分子金属有机笼(MOCs)是通过不同的配体和金属受体之间的配位作用而构建的，可以很好地控制分子的大小、形状、空腔和组成。它们独特而复杂的分子结构使得不同类型的分子间相互作用，包括静电作用、疏水作用、氢键作用、van der Waals作用、π-π作用和主客体作用等都可能在金属有机碳溶液中共存。多种吸引力的协同或竞争相互作用是导致MOCs在溶液中形成胶束、纤维、纳米片、纳米立方体、纳米棒和黑莓等各种超分子结构的激发和丰富的溶液自组装行为的驱动力。为了更好地了解这些高有序结构的形成和设计具有所需性质和功能的超分子结构，人们已经做出了广泛的努力。在这篇综述中，我们试图根据所涉及的物理力的类型从文献中对MOC解决方案中的自组装行为进行分类。
Molecular metal-organic cages (MOCs) are constructed via coordination among diverse ligands and metal acceptors with great control over the size, shape, cavity, and composition. Their unique and complex molecular structures make different types of intermolecular interactions, including electrostatic, hydrophobic, hydrogen bonding, van der Waals, π-π and host-guest interactionsetc., possible to co-exist in MOC solution. The cooperative or competitive interplay of multiple attractive forces is the driving force leading to exciting and rich solution self-assembly behavior of the MOCs into various supramolecular structures, such as micelles, fibers, nanosheets, nanocubes, nanorods, and blackberry structures. Extensive efforts have been made for gaining better understanding on the formation of these higher ordered structures and designing supramolecular structures with desired properties and functions. In this review, we try to sort out the self-assembly behaviors in MOC solutions from literature based on the type of physical forces involved.
