Electrochemical Formation of the Redox-Active Metal-Containing Polymers for Catalytic and Electrocatalytic Applications

Abstract

A convenient electrochemical approach to new redox-active Cu, Pd, Ni -containing polymers of polyamic type with biquinoline (biQ) fragments was elaborated. The comparative analysis of the data obtained revealed the main factors which influence the type of metal coordination unit formed in the polymer: the nature of metal, the number of biQ fragments and conformational rigidity of the polymer backbone as well as the electrolysis conditions. Voltammetric investigation of metal-polymers allows distinguishing the types and relative amounts of metal-coordination units formed. The comparison of the electrochemical data with the results of catalytic tests revealed the guidelines for electrochemical synthesis of efficient catalytic systems.
