Electrochromic and liquid crystalline polycarbonates based on telechelic oligothiophenes

Abstract

The triphosgene carbonate synthesis is adapted as a convenient route towards an alternating main-chain rod/coil polycarbonate based on a telechelic sexithiophene oligomer, yielding an electroactive polymer that is a vibrantly electrochromic material despite the conjugation break. This polymer displays morphological behaviour typical of a liquid-crystalline polymer, with stacking distances between chromophores suitable for potential charge transport applications.
