Supramolecular Chemistry at the Single‐Molecule Level

Abstract

Pulling power: The specific interaction of individual (alkyl) ammonium residues with a resorc[4]arene cavitand that is attached to a gold surface are investigated. Measurements are made by attaching the residue to the cantilever of an atomic force microscope (AFM; see picture). The results confirm that the affinity of the guest for the host depends of their mutual steric compatibility.
