Synthesis, Structure, and Redox Properties of 1,1'-Bis(aryloligothienyl)ferrocenes

Abstract

We succeeded in the synthesis of 1,1′-bis{2-(5-arylthienyl)}ferrocenes as both cathodic and anodic multiple-redox active organic-organometallic hybrid molecules. Characterization of the molecules was performed by physical and spectroscopic means and X-ray crystallographic analyses. The electrochemical properties were examined by cyclic voltammetry. The voltammograms of all compounds showed two oxidation steps derived from the ferrocenium cation and the 5π thiophene radical cation, and two reduction steps derived from 7π thiophene radical anions separated from each other by a bridging ferrocene fragment.
