The electrochemistry of thiol self-assembled monolayers (SAMs) on a hanging mercury drop electrode (HMDE).

Date Published:



The electrochem. of functionalized self-assembled monolayers on Hg is studied by cyclic voltammetry and AC voltammetry. The results suggest that thiols can be adsorbed either chem. or phys. depending on the Hg potential. The transformation between these two states occurs via an oxidn.-redn. process. While a multi-layer of short chemisorbed thiols is formed under pos. potentials than the oxidn.-redn. process, a dense monolayer is self-assembled under more neg. potentials. [on SciFinder(R)]
