TL;DR: A novel donor-acceptor type liquid-crystalline semiconducting copolymer, poly(didodecylquaterthiophene-alt-didodECylbithiazole), which contains both electron-donating quaterthyphene and electron-accepting 5,5'-bith Diazole units, which exhibits excellent electrical characteristics such as field-effect mobilities and bias-stress stability comparable to that of amorphous silicon (a-Si).

TL;DR: It is shown that the morphology of organic semiconductor films deposited on RGO electrodes is similar to that observed in the channel region of the devices and that devices fabricated with RGO electrode have lower contact resistances compared to those fabricated with gold contacts.

TL;DR: Stable uniform performance inkjet-printed polymer transistor arrays, which allow demonstration of flexible full-color displays, were achieved by new ambient processable conjugated copolymer semiconductor, and OTFT devices incorporating this material showed high mobility values.

TL;DR: In this article, an exemplary organic semiconductor copolymer includes a polymeric repeat structure having a polythiophene structure and an electron accepting unit, where the electron acceptance unit has at least one electron-accepting heteroaromatic structure with at least 1 electron-withdrawing imine nitrogen in the hetero-caromatic structure or a thiophene-arylene comprising a C2-30 heteroarromatic structure.

TL;DR: The observation of band-like transport from printed polymer thin films at room temperature from donor-acceptor type thiophene-thiazole copolymer that was carefully designed to enhance the planarity of the backbone and the resulting transfer integral between the macromolecules is reported.
