金属-有机骨架(MOFs)多孔材料的孔结构调节途径

多孔金属-有机骨架（MOFs）材料是近年来发展起来的一种新型功能材料.本文系统综述了MOFs孔结构的调节途径,包括构建分子调节、模板剂调节和反应环境调节控制.通过对有机配体的选择和修饰可调节MOFs的孔结构和孔表面的物理化学性质;而选择具有不同配位构型的金属离子也可以改变MOFs的骨架结构;模板剂通过控制骨架网络结构从而决定MOFs的孔径大小和形状;温度、溶剂等反应条件有时也会在一定程度上影响聚合物的结构.

Approaches to Adjust Pore Structure of Porous Metal-organic Framework Materials

Porous metal-organic frameworks(MOFs) are a novel family of functional materials that have been developed in late years.The approaches to adjust pore structure of MOFs are summarized systemically in this article,including building blocks adjusting,template regulation,and reactive condition control.By the selection and decoration of organic bridging ligands it is possible to adjust the pore structure and pore surface properties.Metal ions with different coordination configuration will form variously structured MOFs with the given ligands.Their pore sizes and shapes can also be determined by templates through their impacts on network structures of MOFs.In addition,the reactive conditions,e.g.temperature,solvents,etc.,might affect the structures of the target polymers to some extend.
