High-Performance Polythiophene Thin-Film Transistors Processed with Environmentally Benign Solvent
Bibliographic record
Abstract
Solution processable organic thin-film transistors (OTFTs) have attracted great attention recently due to their high potentials to dramatically reduce the manufacturing cost for large-area and flexible electronic devices. However, most high performance polymeric semiconductors require chlorinated solvents for their device fabrications, which is not an environmentally friendly manufacturing process. In this article, we describe a facile approach to tuning the solubility characteristics of a high mobility polythiophene system by strategic structure modification and demonstrate significantly improved solution properties in environmentally benign solvents with high field-effect mobility up to 0.18 cm 2 V −1 s −1 . To our best knowledge, this is one of the highest mobility values reported so far for solution-processed OTFTs fabricated from polymeric semiconductors in nonchlorinated solvents. Furthermore, the molecular orientations and structural properties of newly developed polythiophenes were evaluated by both single crystal data of their building blocks and X-ray diffraction (XRD) of their thin films.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
