Journal ArticleDOI
Liquid-crystalline semiconducting polymers with high charge-carrier mobility.
Iain McCulloch,Martin Heeney,Clare Bailey,Kristijonas Genevičius,Iain I. MacDonald,Maxim Shkunov,David Sparrowe,Steve Tierney,Robert Wagner,Weimin Zhang,Michael L. Chabinyc,R. Joseph Kline,Michael D. McGehee,Michael F. Toney +13 more
TL;DR: New semiconducting liquid-crystalline thieno[3,2-b ]thiophene polymers are reported on, the enhancement in charge-carrier mobility achieved through highly organized morphology from processing in the mesophase, and the effects of exposure to both ambient and low-humidity air on the performance of transistor devices.
Journal ArticleDOI
Dependence of Regioregular Poly(3-hexylthiophene) Film Morphology and Field-Effect Mobility on Molecular Weight
R. Joseph Kline,Michael D. McGehee,Ekaterina N. Kadnikova,Jinsong Liu,Jean M. J. Fréchet,Michael F. Toney +5 more
TL;DR: In this article, the authors showed that in-plane π-stacking does not cause the mobility−MW relationship, and that modifying the morphology for a constant number-average molecular weight (MW) by changing the casting conditions or annealing the samples strongly affects the charge transport and morphology in the low-mobility, low-MW films, but has little effect on the high-mogulular poly(3-hexylthiophene).
Journal ArticleDOI
Highly oriented crystals at the buried interface in polythiophene thin-film transistors
TL;DR: In this paper, the authors used X-ray diffraction rocking curves to provide direct evidence for highly oriented crystals at the critical buried interface between the polymer and the dielectric where the current flows in thin-film transistors.
Journal ArticleDOI
Microstructural Characterization and Charge Transport in Thin Films of Conjugated Polymers
TL;DR: The characterization techniques that provide information used to enhance the understanding of structure/property relationships in semiconducting polymers are reviewed.
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.
