Hierarchical self-assembly (HAS) is a multilevel organization process that first assembles elementary molecular units into ordered secondary structures via noncovalent interactions, which further act as the building blocks to form more complex multifunctional superstructures at the next level(s). The HAS strategy has been used as a versatile method for the preparation of soft-matter nanoarchitectures of defined size and morphologies, tunable luminescence, and biological importance. However, such preparation can be greatly simplified if well-defined dynamic structures are employed as the cores that upon linking form the desired nanoarchitectures. Discrete supramolecular coordination complexes (SCCs) with well-defined shapes, sizes, and internal cavities have been widely employed to construct hierarchical systems with functional diversity. This Account summarizes the prevailing strategies used in recent years in the preparation of SCC-based HASs and illustrates how the combination of dynamic metal–ligand coordination with other interactions was used to obtain hierarchical systems with interesting properties.

超分子配位配合物的层次组装

分层自组装（HAS）是一种多级组织过程，首先通过非共价相互作用将基本分子单元组装成有序的二级结构，这些结构进一步充当在下一级形成更复杂的多功能上层结构的构建块。HAS 策略已被用作制备具有确定尺寸和形态、可调谐发光和生物学重要性的软物质纳米结构的通用方法。然而，如果采用明确的动态结构作为核心，在连接时形成所需的纳米结构，则可以大大简化这种制备。具有明确形状、尺寸和内部空腔的离散超分子配位配合物（SCC）已被广泛用于构建具有功能多样性的分层系统。本报告总结了近年来制备基于 SCC 的 HAS 的流行策略，并说明了如何将动态金属配体配位与其他相互作用相结合来获得具有有趣特性的分层系统。
