The production of H2 from sunlight and water has attracted great interest in the development of alternative sources of energy. Mononuclear Co complexes have been designed over the past years for hydrogen production. In order to explore the electronic and steric effects of ligand scaffold on the catalytic properties for H2 evolution by cobalt complex with a pentadentate ligand, N,N-bis(2-pyridinylmethyl)-2,2'-bipyridine-6-methanamine (DPA-Bpy), modifications of the pyridyls in DPA-Bpy with electron-withdrawing and donating groups and their effects on overpotential, turnover frequency, and stability for electro- and photocatalytic H2 production in aqueous solutions will be discussed.
