Electrochromic properties of a poly(dithienylfuran) derivative featuring a redox-active dithiin unit

Abstract

A teraryl monomer containing a 1,4-dithiin-furan central unit has been synthesised and characterised by single crystal X-ray crystallography. The di(thienyl)furan monomer 11 was successfully polymerised electrochemically and shown to possess a lower electrochemical band gap than its terthiophene analogue (1.97 eV cf. 2.11 eV). The electrochromic properties of this polymer proved to be superior to PEDOT, with fast switching and reversible colour transformation at high colour contrast (CE = 212 cm2 C−1cf. 183 cm2 C−1 for PEDOT at 95% optical switch).
