Conductive Polymers: Synergistically Improved Molecular Doping and Carrier Mobility by Copolymerization of Donor–Acceptor and Donor–Donor Building Blocks for Thermoelectric Application (Adv. Funct. Mater. 40/2020)

Abstract

A drop in carrier mobility at high doping levels dramatically hampers the improvement of thermoelectric performance of conductive polymers. In article number 2004378, Hui Li, Lidong Chen, and co-workers propose a new strategy to synergistically improve carrier mobility and molecular doping by randomly copolymerizing donor-acceptor type and donor-donor type building blocks along a polymer backbone. The controllable polymer structure and miscibility with dopants allow random polymers valuable applications as flexible and high-performance thermoelectric materials.
