Abstract

fetched live from OpenAlex

[Extract] Poly(thiophene)s have been an interdisciplinary subject of study over the past two decades 1-5 largely because of their novelty, characteristic electrical and pptical properties, and potential application in electronic devices such as organic field-effect transistors (FETs), 2 chemosensors, 3 electrochemical capacitors, 4 and light-emitting displays (LEDs). 5 Their processability, molecular organization, and electronic and optical properties can be controlled through derivatization of the thienylring. However, the scientific demand for poly(thiophene)s that possess more complex structural motifs is offset by synthetic limitations. For example, preparation of poly-(thiophene)s with functional side chains requires tedious procedures involving the synthesis of monomers. All but a few functional groups are intolerant of the harsh polymerization conditions, with the result that many potential functional poly(thiophene)s simply cannot be prepared.

Teacher imitation

Not 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.
