Catalytic electron drives host-guest recognition.

ABSTRACT: Electron injection is demonstrated to trigger electrocatalytic chain reactions capable of releasing a solvent molecule and forming a redox active guest molecule. One-electron reduction of a hydroxy anthrone derivative (AQH-CH₂CN) results in the formation of an anthraquinone radical anion (AQ˙^-) and acetonitrile (CH₃CN). The resulting fragment of AQ˙^- exhibits high stability under mild reducing conditions, and it has enough reducing power to reduce the reactant of AQH-CH₂CN. Hence, subsequent electron transfer from AQ˙^- to AQH-CH₂CN yields the secondary AQ˙^- and CH₃CN, while the initial AQ˙^- is subsequently oxidized to AQ. Overall, the reactants of AQH-CH₂CN are completel
