Abstract

original image

Three mesoporous metal-organic frameworks (MOFs) with rare corundum-type topology and size-tailored cages are constructed by length-extendable tetratopic ligands. All the MOFs show selective CO2 uptake over N2 and their CO2 uptake capabilities are discriminated with different cage sizes. The MOFs can serve as hosts for encapsulating extra-framework lanthanide cations, and be applicable in column-chromatographic separation for large dye molecules.
