Synthesis and properties of viologen functionalized poly(3‐alkylthienylenes)

Abstract

Viologen functionalized conducting polymers synthesized from the substituted monomers whon in the figure are interesting materials with possible applications in redox or electrocatalysis, sensors, and electrochromic devices. Monomers and polymers with various numbers of methylene groups separating the thiophene units and the redoxactive viologen moieties have been synthesized and characterized. magnified image
