Metallo-supramolecular polymer networks (MSPNs) are fabricated from the crosslinking of polymers by discrete supramolecular coordination complexes. Due to the availability of various coordination complexes, e. g., 2D macrocycles and 3D nanocages, the MSPNs have been recently developed with broadly tunable visco-elasticity and enriched functions inherited from the coordination complexes. The coordination complexes possess enriched topologies and unique structural relaxation dynamics, rendering them the capability to break the traditional tradeoffs of polymer systems for the design of materials with enhanced mechanical performance. The structure-property relationship studies are critical for the material-by-design of MSPNs, while the spatiotemporal investigations are desired for the exploration of dynamics information. The work summarizes recent studies on the unique ligand-exchange kinetics and the multi-level structural relaxation dynamics of MSPNs. The MSPNs' mechanical properties can be quantitatively correlated with the dynamics for understanding the structure-property relationship. This concept will not only serve to attract more researchers to engage in the study of the structure-activity relationship of MSPNs but also inspire innovative research findings pertaining to the application of MSPNs.
金属超分子聚合物网络（MSPNs）是由离散的超分子配位络合物交联聚合物制成的。由于各种配位络合物的存在，例如二维大环和三维纳米笼，MSPNs最近已被开发出来，具有广泛可调的粘弹性和从配位络合物继承而来的丰富功能。配位络合物具有丰富的拓扑结构和独特的结构弛豫动力学，使其有能力打破聚合物体系在设计具有增强机械性能的材料时的传统权衡。结构-性能关系研究对于MSPNs的材料设计至关重要，而时空研究对于探索动力学信息是必要的。这项工作总结了最近关于MSPNs独特的配体交换动力学和多级结构弛豫动力学的研究。MSPNs的机械性能可以与动力学进行定量关联，以理解结构-性能关系。这一概念不仅将吸引更多研究人员参与MSPNs结构-活性关系的研究，还将激发与MSPNs应用相关的创新研究成果。
