The use of hydrogen as potential clean and renewable fuel requires development of catalysts for hydrogen production. We have demonstrated electro- and photocatalytic hydrogen production by molecular Co complexes with pentadentate ligands derived from N,N-bis(2-pyridinylmethyl)-2,2'-bipyridine-6-methanamine (DPA-Bpy) and shown that the modifications of pyridyls with isoquinoline groups result in significant lower overpotential and higher TOF for electrocatalytic H<sub>2</sub> production. In order to understand the structure-function relationship on catalytic properties such as overpotential and TOF for hydrogen production, modification of the DPA-Bpy-derived pentadentate ligands and their effects on catalysis will be discussed.
