Abstract

original image

Magic ink: The chemical reactivity of a bromo-terminated self-assembled monolayer immobilized on an insulating substrate is quantified from the time evolution of patterns formed during the local reduction of the SAM (see picture; bpy=2,2′-bipyridine). The potential of this lithographic strategy to determine the reactivity of the self-assembled monolayer is described and compared to surface interrogation by electrochemical microscopy.
