A conjugated polymer with high planarity and extended π-electron delocalization via a quinoid structure prepared by short synthetic steps

Abstract

An attractive synthetic strategy for incorporating a quinoidal molecule into a conjugated polymer backbone with three short steps is reported here. The quinoidal polymer, PQuBTV, exhibited high planarity and extended conjugation. As a result, ambipolar charge carrier mobilities of 0.52 cm² V⁻¹ s⁻¹ for holes and 0.53 cm² V⁻¹ s⁻¹ for electrons were observed in field-effect transistor devices.
