Polymers with redox properties: materials for batteries, biosensors and more

This minireview highlights the recent advances in the chemistry, characterization and applications of polymers with redox properties. The development of new redox polymers is clearly dominated by the interest in the area of batteries and biosensors. However, new applications in energy, materials science and biomedical fields have emerged together with the development of new polymeric materials. Historical works in the areas of ferrocene containing polymers and polyaniline conducting polymers have evolved today in a high number of innovative macromolecular structures whose singular properties indicate a bright future. The goal of this manuscript is to illustrate the state-of-the art in the development of polymers with redox properties and to highlight the most popular applications.
