Even though the HG binding is reduced at higher pH, the host remains on the electrode. We could confirm this assumption by the reabsorption of the guests after catalysis more than three times, which we demonstrated in several experiments in both, aqueous and organic solvents (Figures ). Moreover, the reabsorption is not only accessible with the same guests but also with another guest: Guest 1 and guest 2 can be exchanged after catalysis on a sample that was initially functionalized with the other guest, which we demonstrated by absorbing the used electrodes with fresh exchanged guests. Both reabsorption experiments showed distinctive redox peaks of the related other guest (Figure ).
