In order to explain that behavior, we studied the electrochemical properties of a fluorinated diazonium salt that exhibits a strongly passivating behavior on various micro-crystalline gold electrodes. We propose here that each sub-peak observed in CV corresponds to the reduction of the compound on a distinct crystallographic site %G English %L cea-01056555 %U https://cea.hal.science/cea-01056555 %~ CEA %~ CNRS %~ UNIV-ANGERS %~ PUBNIMBE
