Understanding how to improve catalysts for interconversions between water and hydrogen and oxygen is of great interest for energy storage or conversion, and organic transformations. Here, our research on water oxidation catalysts (WOC) and related species will be described. The interaction of Ir-based WOC with oxidants is a subject of ongoing research by our group1 and many others.2-5 Our efforts to overcome stability and activity issues will be described. We use a combination of variations in ligand architecture and central metal(s), as well as studying a variety of redox methods, from electrochemistry to sacrificial oxidants and reductants. Ligands capable of proton transfer and/or hydrogen bonding are being applied to WOC6 as well as reactions involving hydrogen formation and cleavage.7  (1) JACS 2011 , 133, 19024; (2) Green Chem. 2011 , 13, 3360; (3) JACS 2013 , 135, 10837; (4) JACS 2014 , 136, 3981; (5) Eur.
