Nanostructured monolayer of azobenzene derivs. was prepd. on C materials. The method is based on the electrochem. redn. of a specific silyl-protected aryl diazonium salt followed by a deprotection step and a click chem. coupling reaction. This procedure leads to a robust modification of the surface where mol. entities are placed in a frozen structuration thanks to the covalent nature of the modification. The photo-switchable properties of the surface were examd. by electrochem. using different redox probes. UV-visible light irradn. provides an easy way to reversibly modulate the permeability in a monolayer film grafted onto C materials. [on SciFinder(R)]
