N2 - Electroactive and conductive polymers based on transition metal complexes with salen-type ligands are of interest as potential materials for energy storage and solar energy conversion. The easily tunable structure of monomers allows to modify polymer properties by changing either the central metal atom or the ligand substituents. Herein we report the photoelectrocatalytic activity of [MII(L)]n complexes, where M is Ni, Cu or Pd, and L is a tetradentate N,N,O,O salen-type ligand, in the reduction of molecular oxygen to hydrogen peroxide in water solutions on polymer-coated ITO electrodes.
