Pyridinium Conjugated Ferrocenes with Thien and Bithien Bridges: Synthesis and Electrochemical Properties

Three di‐ and tri‐branched pyridinium salts with ferrocene ends and thienyl or bithienyl bridges, (E,E)‐N‐methyl‐2,4,6‐tris{2‐[5‐(2‐ferrocenylvinyl)thien‐2‐yl]vinyl} pyridinium iodide, (E,E)‐N‐methyl‐2,6‐bis‐ {2‐[5′‐(2‐ferrocenylvinyl)‐2,2′‐bithien‐5‐yl]vinyl} pyridinium iodide, and (E,E)‐N‐methyl‐2,4,6‐tris‐{2‐[5′‐(2‐ferrocenylvinyl)‐2,2′‐bithien‐5‐yl]vinyl}pyridinium iodide, were designed and successfully synthesized. The electrochemical properties of these compounds were primarily investigated, showing that most of these multiferrocenyl pyridinium salts are potential electrochemical molecular materials with good oxidation‐reduction reversibility.
