Poly[trans-bis(3,4-ethylenedioxythiophene)vinylene]: a low band-gap polymer with rapid redox switching capabilities between conducting transmissive and insulating absorptive states

Abstract

trans-Bis(3,4-ethylenedioxythiophene)vinylene is synthesized and electrochemically polymerized to give poly[trans-bis(3,4-ethylenedioxythiophene)vinylene](PBEDOT-V) which exhibits a band gap of 1.4 eV and can be rapidly switched between insulating deep purple absorptive and highly conducting light blue transmissive states.
