A rotaxanescaffold incorporating two dithiolane anchoring units for the modification of gold surfaces has been functionalized with multiple copies of a redox unit, namely ferrocene. Surfacemodification has been first assessed at the single molecule level by atomic force microscopy (AFM) and scanning tunneling microscopy (STM) imaging, while tip enhanced Raman spectroscopy (TERS) provided the local
A rigid 3D scaffold in a 2D world! A mixed [5:1] fullerenehexaadduct 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). Ultrafastcyclicvoltammetry investigations revealed that both intramolecular electron hopping and molecular motions influence the electron transfer from
