Catch it if you can! Redox-active resorcin[4]arene cavitands with quinone walls can be reversibly reduced to the hydroquinone form, influencing their host–guest complexation strength. Specifically, a top-covered triptycenequinone cavitand forms kinetically stable complexes with cycloalkanes; this complexation is weaker in the reduced hydroquinone form.
