Dual p- and n-type doping in an acid sensitive alternating bi(ethylenedioxythiophene) and pyridine polymer

Abstract

Poly[2,5-bis(3,4-ethylenedioxy-2-thienyl)pyridine] exhibits multi-color electrochromism via easily accesible p- and n-type doping, and can be switched between a pale blue reduced state, a red neutral state, and a blue–purple oxidized state.
