The Center for Molecular Electrocatalysis uses frustrated Lewis acid-base pairs consisting of Lewis acidic transition metal centers and pendant amine bases for the heterolytic oxidation of H2. The amine bases are restricted from interacting with the metal centers through the ligand architecture, creating the FLP environment. This talk will describe our efforts in designing molecular electrocatalysts for hydrogen oxidation of the type (CpX)Fe(PRNR'PR)(H). In these complexes the substituent on the CpX ring (i.e. X) and the substituent on the nitrogen atom (i.e. R') are used to tune the relative acidity and basicity of the FLP for optimum catalytic activity.
