The exquisite efficiency of biological systems relies on the use of reactivity-enhancing tools to perform chemical reactions with unrivaled efficiency. Among these tools, redox cofactors present near metalloenzymatic active sites provide electron storage and release to assist the neighboring metal center in performing the reactions. Emulating such systems, the development of catalysts bearing redox-active ligands is a blossoming research field. We will present our results on tailoring redox-active ligand platforms to design systems that can perform selective electron transfer and redox catalysis.
