I am deeply honored of being the 2018 winner of the Manuel M. Baizer Award, which celebrates achievements in electroorganic chemistry in a broad sense. Personally, I have always been fascinated by the challenges associated with the understanding of mechanisms and properties of molecular systems, especially organic molecules. In this context, I followed the steps of my mentor, the late Professor Elio Vianello, as well as those of others I had the privilege to work or discuss with. In other words, I have always been an advocate of the molecular approach to address scientific problems and thus of the importance of explaining the fine details of electrochemical reactions on a true molecular basis. Molecular electrochemistry is known to embrace a number of topics, such as electron-transfer (ET) induced transformation of molecules, associated chemical reactions, control of long-range and mediated ET reactions, and electrochemistry on electrodes and modified electrodes. Molecules can be seen in different ways. Generally, molecules are hard objects, characterized by well-defined shapes and minor structural variations upon ET. Sometimes, however, they are fragile in the sense that ET causes cleavage of a σ-bond, resulting in the formation of two molecular fragments. More complex molecular systems, on the other hand, can be seen as soft or hard-soft. This is especially true in ligand-protected gold nanoclusters, i.e., molecules in which a hard gold core is protected by a soft interface of flexible ligands that form a nanoenvironment through which the core interacts with the outside medium and thus, ultimately, redox partners. In this presentation, I will describe how molecular electrochemistry concepts can be applied to understand the ET behavior and properties of both fragile and soft molecular systems. Examples of how electrochemical results can be nicely integrated with data from other techniques or methods will also be described.
