摘要：
A self-assembled monolayer (SAM) of 6-thioguanine (6TG) was formed on the hanging mercury drop electrode, under open circuit potential, from 6TG solutions. The SAM has been characterized by cyclic voltammetry under both in situ and ex situ conditions and the experimental data reveal that the film is a densely packed structure of chemisorbed (mercury-thiol) molecules. The presence of this SAM has no influence on the rate of outer-sphere electrode reactions but strongly inhibits inner-sphere processes. The electrode reaction involving the Fe(CN)(6)(3-/4-) couple appears reversible in a hanging mercury drop electrode coated by the 6TG-SAM.
