摘　　要：金属有机框架(MOFs)因其结构的灵活可调性在光催化领域受到广泛关注。桥接配体作为MOFs捕获光的天线在光催化中扮演着不可或缺的角色。从桥接配体与MOFs本体之间的架构关系出发,对本征MOFs的桥接配体进行功能化改性,有望实现MOFs更多样化的结构和独特的功能,进而优化光生载流子的“产生-分离-利用”途径。基于MOFs的配体工程,总结了不同配体的改性策略及其光催化反应机制,详细说明了功能调控对MOFs材料催化性能的影响,并针对该策略提出了相应的见解和展望。Metal-organic frameworks(MOFs)have attracted extensive attention in the field of photocatalysis due to their flexible and adjustable structures.Bridging ligands play an indispensable role in photocatalysis as antennas for MOFs to capture light.Based on the architectural relationship between the bridging ligand and the MOFs ontology,the functionalization of the bridging ligand of intrinsic MOFs is expected to achieve more diverse structures and unique functions of MOFs,and then optimize the“generation-separation-utilization”pathway of photogenerated carriers.Based on the ligand engineering of MOFs,this paper summarizes the modification strategies of different ligands and their photocatalytic reaction mechanisms in an orderly manner,explains in detail the influence of functional regulation on the catalytic performance of MOFs materials,and puts forward corresponding insights and prospects for this strategy.
