An electrochemical study of Au electrodes electrografted with azobenzene (AB), Fast Garnet GBC (GBC) and Fast Black K (FBK) diazonium compounds is presented. Electrochemical quartz crystal microbalance, ellipsometry and atomic force microscopy investigations reveal the formation of multilayer films. The elemental composition of the aryl layers is examined by X-ray photoelectron spectroscopy. The electrochemical measurements reveal a quasi-reversible voltammogram of the Fe(CN)6 (3-/4-) redox…

In this paper, gold and glassy carbon (GC) electrodes were electrochemically grafted with anthraquinone (AQ) groups derived from Fast Red AL salt via electrochemical reduction of AQ diazonium
Electrochemical Attachment of Diazonium-Generated Films on Nanoporous Gold.
Results indicate that a thick but highly defective molecular film forms with a mixture of strongly and weakly bound molecules in nanoporous gold.
Voltammetric sensor based on long alkyl chain tetraalkylammonium ionic liquids comprising ascorbate anion for determination of nitrite
Cyclic voltammetric investigations revealed electrostatic interactions between the electrochemical probes and the modified surface, proving that a positive charge was established at the film surface, ensuring that negatively charged species such as nitrite can be pre-concentrated on the surface of presented modified electrodes.
Azo group(s) in selected macrocyclic compounds
Azobenzene derivatives due to their photo- and electroactive properties are an important group of compounds finding applications in diverse fields. Due to the possibility of controlling the trans–cis


Some evidence for the formation of an azo bond during the electroreduction of diazonium salts on Au substrates.
The spectroscopic evidence suggests the formation of N=N bonds tethering the complexes to Au, and the surface coverage of the azo-bonded osmium complexes strongly depends on the electrode potential.
Characterization of the deposition of organic molecules at the surface of gold by the electrochemical reduction of aryldiazonium cations.
The deposition of 4-X phenyl groups on polycrystalline gold electrode was achieved by the electrochemical reduction of the corresponding 4-substituted phenyldiazonium tetrafluoroborate salts in anhydrous acetonitrile media and showed that the formation of multilayers is possible and that a significant fraction of the deposited material remained at the electrode surface, even following ultrasonic treatment.
Electrochemical Behavior of Azobenzene Self-Assembled Monolayers on Gold
The self-assembly and electrochemical properties of a novel thiol-functionalized azobenzene derivative were studied on gold electrodes by cyclic voltammetry. The compound was
