Structuring Redox Polymers Poly[M(Schiff)] (M = Ni,Pd; Schiff = Schiff Bases) on a Molecular Level: Methods and Results of an Investigation

This work is devoted to a consideration of methods of electrochemical synthesis of redox polymers polyM(Schiff)], where “M” is Ni, or Pd and “Schiff” stands for a four-dentate Schiff base, with a controlled distribution of structural elements (stacks) over the electrode's surface for the optimization of the transport of charge-compensating ions, which is the stage that determines the charge transfer rate in the system under consideration. It is shown that the structuring of these polymers on a molecular level by means of a purposeful selection of the composition of the initial compounds and the conditions of synthesis—the potential of formation and the nature of the solvent and supporting electrolyte—makes it possible to a considerable extent accelerate the charge transfer process in the polymers and improve stability of their electrochemical characteristics.
