To boost the design of microporous solids, we integrated a two-faced shape (as in cucurbiturils and cyclodextrins) into the building blocks of framework materials. Reported herein is a planar tritopic carboxyl linker with secondary tripod donors sprouting off both sides at the core region. The two-faced, barrel-like core region imparts a rugged 3D character to the linker architecture, obviating close packing and creating complex-shaped cavities in an Eu(iii)-carboxylate network. The merits extend beyond the interesting shape of the multiple tripod: e.g., the two sets of sulfur tripods at the barrel region, together with the triazine center, offer a rich array of donors for adsorbing Hg(ii) ions. The microporous solid also removes iodine from vapor and water, and can be easily cycled in column chromatography. [ABSTRACT FROM AUTHOR]
