Dithienosilole− and Dibenzosilole−Thiophene Copolymers as Semiconductors for Organic Thin-Film Transistors
Abstract
The synthesis and physicochemical properties of a new class of thiophene/arenesilole-containing pi-conjugated polymers are reported. Examples of this new polymer class include the following: poly(2,5-bis(3',3' '-dihexylsilylene-2',2' '-bithieno)thiophene) (TS6T1), poly(2,5'-bis(3' ',3' ''-dihexylsilylene-2' ',2' ''-bithieno)bithiophene) (TS6T2), poly(2,5'-bis(2' ',2' ''-dioctylsilylene-1' ',1' ''-biphenyl)thiophene) (BS8T1), and poly(2,5'-bis(2' ',2' ''-dioctylsilylene-1' ',1' ''-biphenyl)bithiophene) (BS8T2). Organic field-effect transistors (OFETs) with hole carrier mobilities as high as 0.02-0.06 cm2/V s in air, low turn-on voltages, and current on/off ratios >105-106 are fabricated using solution processing techniques with the above polymers as the active channel layer. OFETs based on this polymer class exhibit excellent ambient operational stability.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
