The self-assembly of alkanethiols on gold surfaces from micellar aqueous solutions was investigated using Triton X-100, sodium dodecylsulfate, and cetyltrimethylammonium bromide as representative nonionic, anionic, and cationic surfactants, respectively. The surfactant solutions solubilized the otherwise water-insoluble alkanethiols, which self-assembled on gold to form organized assemblies very similar to those prepared using the conventional procedures, i.e., exposure of the gold surface to a nonaqueous solution of the alkanethiol. The resulting derivatized gold electrodes exhibited typical electrochemical properties, such as low capacitance values and substantial blocking of the voltammetric reduction of Ru(NH3)63+. The concentration of surfactant was found to have a profound effect on the rate of alkanethiol chemisorption.
