Caught in a barrel : AFM studies indicate that the host–guest complexes formed between β‐barrel pores and polymer blockers are pseudorotaxanes. The nonstatistical location of the contracted supramolecular barrels on the polymers indicates that the sticky polymer templates insert quickly into the β barrels (see schematic representation) and then undergo slow motion through the barrels.
