The rational choice of transition-metal ion and ligand platform provides the ability to design molecules with highly tuned reactivity, solubility, and stability properties. This presentation will describe applications pertaining to flow battery technologies and biomolecule modification strategies that are mediated by transition metal complexes with carefully tailored stability and reactivity profiles. Work detailing a new approach to non-aqueous redox-flow battery electrolyte design using transition metal complexes supported by electrochemically stable, all-inorganic trimetaphosphate ([P3O9]3–) anions will be highlighted. Cobalt and vanadium bistrimetaphosphate complexes have favorable properties for flow-battery applications including reversible redox chemistry, high stability toward electrochemical cycling, and high solubility in MeCN, rendering this class of species as promising building blocks for flow-battery chemistries. The second part of the talk will present a series of robust, well-defined, isolable organometallic complexes that serve as versatile reagents for the incorporation of a wide range of both organic and inorganic moieties to biomolecules.
