Abstract

One ring to rule them out: Preorganization of simple polyamine podands in the presence of nitrate or sulfate affords a new kind of C3-symmetrical supramolecular ring. Although not rigid, the ring's cavity is stabilized by a network of noncovalent interactions and displays an amazing level of selectivity for these two anions in a number of competitive anion/solvent environments.
