Fine‐Tuning Conformational Motion of a Self‐Assembled Metal–Organic Macrocycle by Multiple CH⋅⋅⋅Anion Hydrogen Bonds

Abstract

Anion switches: A bistable self-assembled metal–organic macrocycle undergoes intramolecular conformational motion that is switched reversibly with anions by multiple hydrogen-bonding interactions (see picture; Pd orange, N blue, O red). The molecular bowl fixed with a nitrate anion could be freed to a partial chair by adding a tetraphenylborate anion.
