| Summary: | The surface modification by organics has been booming over the past twenty years in the context of the development of 2D nanomaterials for a wide range of applications. The diazonium salt chemistry represents a valued approach since it allows the covalent attachment, under mild experimental conditions, of functional moieties to various substrates. The potential of this method can be greatly enhanced by exploiting it to prepare reactive organic layers intended for the coupling of more complex molecular structures. This two-step approach, called "post-functionalization", has been successfully exploited to provide working surfaces for a wide variety of applications such as sensors, catalysis, energy storage or nanoelectronics. This review aims to detail all the chemical coupling methods implemented on modified substrates
via
the diazonium chemistry (352 references), with an emphasis on the experimental conditions used and on the efficiency of the couplings. An overall table collects the references, classified by coupling method, modified substrate and targeted application.
Tailored 2D-nanomaterials can be prepared from diazonium electrografted surfaces through a wide range of post-functionalization approaches. |

| Bibliography: | Christelle Gautier is a CNRS researcher in MOLTECH-Anjou laboratory at the University of Angers (France). She received her PhD in Physical chemistry from the University of Le Mans in 2006. After a post-doctoral position in Montréal (Canada) with Daniel Bélanger and another one in the Commisariat à l'énergie Atomique in Saclay (France), she started her actual CNRS position in 2010. Her research interests concern the immobilization of organic molecules on surfaces and the study of the impact of these molecules confinement of on their properties. Isidoro Lopez received his PhD in 2013 from the Institute of Chemical Research of Catalonia and Universitat Rovira i Virgili working under the supervision of Prof. Antoni Llobet in the study of new water oxidation electrocatalysts. At the Université d'Angers, he worked on the functionalization of conducting surfaces via the controlled reduction of diazonium salts. He is currently a postdoctoral researcher at the Université de Pau et des pays de l'Adour, where he analyses interphases in lithium solid-state batteries. The research interests of Isidoro Lopez include the modification of electrode surfaces and the spectroelectrochemical study of processes at electrified interfaces. Tony Breton was born in La Rochelle (France) in 1977. He received his PhD in organic electrosynthesis from the university of Poitiers in 2004. After a 1 year postdoctoral research study on the electrochemical modification of surfaces with Professor Daniel Belanger (Montreal - Canada), he joined the MOLTECH-Anjou laboratory at the University of Angers (France) where he is currently professor. His current work concerns the elaboration and characterization of functionalized conductive surfaces in the aim of establishing controlled structure-properties relationships. |
