Thieno[3,2-b]thiophene-Diketopyrrolopyrrole-Containing Polymers for High-Performance Organic Field-Effect Transistors and Organic Photovoltaic Devices
Hugo Bronstein,Zhuoying Chen,Raja Shahid Ashraf,Weimin Zhang,Junping Du,James R. Durrant,Pabitra Shakya Tuladhar,Kigook Song,Scott E. Watkins,Yves Geerts,MM Martijn Wienk,René A. J. Janssen,Thomas D. Anthopoulos,Henning Sirringhaus,Martin Heeney,Iain McCulloch +15 more
TL;DR: The synthesis and polymerization of a novel thieno[3,2-b]thiophene-diketopyrrolopyrrole-based monomer is reported, which has a maximum hole mobility of 1.95 cm(2) V(-1) s(-1), which is the highest mobility from a polymer-based OFET reported to date.
Journal ArticleDOI
Molecular origin of high field-effect mobility in an indacenodithiophene–benzothiadiazole copolymer
Xinran Zhang,Hugo Bronstein,Auke Jisk Kronemeijer,Jeremy Smith,Youngju Kim,Youngju Kim,R. Joseph Kline,Lee J. Richter,Thomas D. Anthopoulos,Henning Sirringhaus,Kigook Song,Martin Heeney,Weimin Zhang,Iain McCulloch,Dean M. DeLongchamp +14 more
TL;DR: It is argued that charge transport in high-mobility semiconducting polymers is quasi one-dimensional, that is, predominantly occurring along the backbone, and requires only occasional intermolecular hopping through short π-stacking bridges.
Journal ArticleDOI
Systematic improvement in charge carrier mobility of air stable triarylamine copolymers.
Weimin Zhang,Jeremy Smith,Rick Hamilton,Martin Heeney,James Kirkpatrick,Kigook Song,Scott E. Watkins,Thomas D. Anthopoulos,Iain McCulloch +8 more
TL;DR: A strategy to prepare fully air stable, amorphous semiconducting polymers which can achieve charge carrier mobilities in the range of 0.04 cm(2)/(V s) remaining over a period of over 3 months in ambient conditions is reported.
Journal ArticleDOI
Random benzotrithiophene-based donor–acceptor copolymers for efficient organic photovoltaic devices
Christian B. Nielsen,Raja Shahid Ashraf,Bob C. Schroeder,Pasquale D'Angelo,Scott E. Watkins,Kigook Song,Thomas D. Anthopoulos,Iain McCulloch +7 more
TL;DR: A series of benzotrithiophene-containing random terpolymers for polymer solar cells is reported, where the absorption profile and the frontier energy levels are optimized and maximum power conversion efficiencies are nearly doubled.
Journal ArticleDOI
Liquid crystalline blue phase I observed for a bent-core molecule and its electro-optical performance
TL;DR: In this paper, the liquid crystalline blue phase I (BP I) was observed for a nematogenic achiral bent-core molecule doped with a small percentage of a chiral additive with a high twisting power.
