Molecular Motion Inside an Adsorbed [5:1] Fullerene Hexaadduct Observed by Ultrafast Cyclic Voltammetry

A rigid 3D scaffold in a 2D world! A mixed [5:1] fullerene hexaadduct that bears ten peripheral ferrocene redox subunits has been anchored onto a gold surface (see picture, green: iron, black: carbon, white: hydrogen, red: oxygen, blue: nitrogen). Ultrafast cyclic voltammetry investigations revealed that both intramolecular electron hopping and molecular motions influence the electron transfer from the ferrocene moieties to the electrode.
