AFM Snapshots of Synthetic Multifunctional Pores with Polyacetylene Blockers: Pseudorotaxanes and Template Effects

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.
