Redox-switchable intramolecular π-π-stacking of perylene bisimide dyes in a cyclophane.
Molecular actuation by stepwise electrochemical reduction is demonstrated for a cyclophane that exhibits a pronounced conformational transition from a closed cavity with cofacially stacked PBIs in the neutral state to an expanded open cavity in the three- and fourfold reduced state.
