title: Spectroscopic and atomic force microscopy characterization of the electrografting of 3,5-bis(4-diazophenoxy)benzoic acid on gold surfaces.
abstract: The synthesis of a bipodal diazonium salt, 3,5-bis(4-diazophenoxy)benzoic acid, and the study of its electrochemical deposition on gold surfaces is presented. The presence of the organic layer on the gold surface was characterized using atomic force microscopy and X-ray photoelectron spectroscopy, demonstrating the presence of phenyl groups, indicative of the grafted layer as well as the formation of multilayers, dependent on the electrografting conditions.
