Stuck like Glue

Host–guest interactions have been exploited to create new linear and cyclic AABB supramolecular polymers composed of tetraphosphonate cavitands and N-methylpyridinium salts.

Enrico Dalcanale and co-workers, Parma, Italy, have designed the new polymers by controlling the flexibility of the ditopic guest spacer, the solvent, and the concentrations used in the system. Solid-state studies have shown that linear polymerization is preferred.
