摘要
Metal-organic frameworks(MOFs),assembled via coordination bonds between metal nodes and organic linkers,feature threedimensional(3D)crystalline frameworks,intrinsic high porosity,precise molecular/atomic arrangement,and tunable chemical reactivity[1].Despite the synthesis of over 100,000 distinct MOF structures for applications spanning from energy to healthcare,their widespread use remains constrained by several challenges.One major concern is the introduction of mesopores with rational structures and pore sizes into the inherently microporous MOFs(with pore sizes smaller than 2 nm),critical to applications involving large molecules[2,3].
