However, strong coupling also implies that the diagnostic redox peaks of the guest in cyclic voltammetry (CV) experiments would be absent, similar to the case with graphite-conjugated molecules that lack clear redox peaks in CV experiments. Indeed, we did not observe redox peaks for the ruthenium-based guests bound to 1 on gold at the respective redox potentials found in solution (Figure ), even as a low catalytic current was observed from the HGC of guest 2 with host 1 on dodecanethiol-poisoned gold substrates (Figure ).
