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.

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).

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.

TL;DR: The characterization techniques that provide information used to enhance the understanding of structure/property relationships in semiconducting polymers are reviewed.

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.
