Abstract
A monolayer constituted by chemisorbed 6-thioguanine and physisorbed guanine molecules was formed on a hanging mercury drop electrode from deoxygenated solutions of 6-thioguanine (6TG) and guanine (G). The mixed monolayer was characterized by chronoamperometry, cyclic voltammetry, and phase-sensitive ac voltammetry under in situ conditions, and the experimental data revealed a compact packing of molecules in the film. Ex situ measurements in the presence of dissolved oxygen proved that the mixed monolayer is stable in solutions lacking 6TG and G.
