Nevertheless, these results show that our immobilization strategy of molecular electrocatalysts using HGCs can be employed to bind active catalysts to electrodes. Moreover, this strategy was effectively used in organic electrolyte, which is notable considering the general competition for occupying the host cavity between guests and solvent molecules. This observation underlines the strong adsorption interaction between the guest molecules and the surface bound hosts. Additional soaking experiments of the HGC in organic solvents used in electrochemical catalysis revealed hours of HGC stability in methanol, acetonitrile, dichloromethane and toluene, indicating that a wide range of electrocatalytic conditions are compatible with this approach (Figures and).
