Attached to gold: Au electrodes are electrografted with azobenzene (AB), Fast Garnet GBC (GBC), and Fast Black K (FBK) diazonium compounds (see picture) to compare the surface grafting and electrochemical behavior of aryl-modified Au electrodes. Multilayer formation is confirmed by a range of techniques. The strongest blocking effect is observed for the AB-modified Au electrodes.
