Anion-directed self-assembly of flexible ligands into anion-specific and highly symmetrical organic solids

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 number of competitive anion/solvent environments. Two interpenetrating networks of nano-sized voids connected with channels contain a large number of included guest molecules in the crystal structure.
