金属有机框架材料(MOFs)通过金属-有机配体的精准组装,实现结构与功能的原子级调控。而可控自由基聚合基于单体反应活性和链动力学的动态调控,优化分子量分布与机械性能。尽管两者在反应机理、应用场景等方面存在本质差异,但均表现出分子层面的设计灵活性与动态响应能力,这使其在交叉应用中能够突破单一体系的固有局限。MOFs利用其孔道结构和金属节点调控可控自由基聚合反应过程,而可控自由基聚合在MOFs框架聚合功能高分子层保护其活性位点或优化其性能。聚焦MOFs与可控自由基聚合的交叉融合应用研究,系统综述了二者协同作用的最新进展,总结“MOF结构设计-可控自由基聚合策略”的双驱协同模式,加深理解无机-有机界面相互作用机制,为新型功能材料(如兼具高催化活性、动态响应性及功能可设计性等)的开发提供一定的参考。
Metal-organic frameworks (MOFs) achieve atomic-level control over their structure and functionality through the precise assembly of metal-organic ligands,whereas controlled free radical polymerization emphasizes the optimization of molecular weight distribution and mechanical performance via dynamic regulation rooted in monomer reactivity and chain kinetics.Although the two systems exhibit fundamental differences in reaction mechanisms and application domains,they both demonstrate molecular-level design flexibility and dynamic responsiveness,enabling cross-application strategies to overcome inherent limitations of single systems.MOFs can utilize their pore structures and metal nodes to control the process of free radical polymerization.Conversely,functional polymer layers can be polymerized on MOFs' framework by controlled free radical polymerization to optimize theri performance or protect their active sites.This paper focused on the combination of MOFs and controlled free radical polymerization,systematically reviewing the latest progress of their synergistic effects.It summarized the dual-drive synergistic model of ‘MOF structure design-controlled free radical polymerization strategy’,deepening the understanding of inorganic-organic interfacial interaction mechanisms and providing valuable insights for developing novel functional materials with integrated high catalytic activity,dynamic responsiveness,and functional designability.
