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 CO 2 uptake over N 2 and their CO 2 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.
