Inspired by the cooperative multi-metallic activation in metalloenzyme catalysis, artificial enzymes as multi-metallic catalysts have been developed for improved kinetics and higher selectivity. Previous models about multi-metallic catalysts, such as cross-linked polymer-supported catalysts, failed to precisely control the number and location of their active sites, leading to low activity and selectivity. In recent years, metallopolymers with metals in the sidechain, also named as sidechain metallopolymers (SMPs), have attracted much attention because of their combination of the catalytic, magnetic, and electronic properties of metals with desirable mechanical and processing properties of polymeric backbones. Living and controlled polymerization techniques provide access to SMPs with precisely controlled structures, for example, controlled degree of polymerization (DP) and molecular weight dispersity (), which may have excellent performance as multi-metallic catalysts in a variety of catalytic reactions. This review will cover the recent advances about SMPs, especially on their synthesis and application in catalysis. These tailor-made SMPs with metallic catalytic centers can precisely control the number and location of their active sites, exhibiting high catalytic efficiency.
受金属酶催化中协同多金属活化的启发，作为多金属催化剂的人工酶已被开发出来，以改善动力学并提高选择性。以往关于多金属催化剂的模型，如交联聚合物负载催化剂，未能精确控制其活性位点的数量和位置，导致活性和选择性较低。近年来，侧链含有金属的金属聚合物，也被称为侧链金属聚合物（SMPs），因其将金属的催化、磁性和电子性质与聚合物主链所需的机械和加工性质相结合而备受关注。活性聚合和可控聚合技术使人们能够获得具有精确可控结构的SMPs，例如可控的聚合度（DP）和分子量分散度（），它们在各种催化反应中作为多金属催化剂可能具有优异的性能。本综述将涵盖SMPs的最新进展，特别是它们在催化领域的合成与应用。这些具有金属催化中心的定制SMPs能够精确控制其活性位点的数量和位置，展现出高催化效率。
