Functionalization of electrode surfaces with monolayers of azocompounds and gold clusters [link]Paper  doi  abstract   bibtex   
Properties of monolayers of azocrown compound self-assembled on gold substrates were studied using voltammetry and scanning tunneling microscopy. The surface concentrations of this compound in monolayers were determined from the area of the voltammetric reduction peaks. The area per one molecule estimated from voltammetry experiments is 0.65 nm(2). This value was comparable with the limiting molecular area of the compound in the Langmuir-Blodgett film at the air-water interface. We also observed the presence of gold clusters and other gold structures by STM when a gold electrode modified with azocrown compound was dipped into the tetrachloroaurate solution. Even better spectra of clusters were obtained following one voltammetric scan in the range 0.5 to -0.6 V. After more cycles or if we condition the electrode at 0.4 V the clusters aggregate into wires.
