Computational study of PEDOT derivatives: reducing air stability to satisfy the self-doping criteria of transparent conjugated polymers
Bibliographic record
Abstract
PEDOT has been one of the most extensively studied conjugated polymers due to its unique combination of good transparency and high electrical conductivity, making it a promising alternative to ITO electrodes. With the aim of designing more conducting and transparent chains, we provide here a state-of-the-art quantum-chemical (TD)-DFT analysis to investigate whether significant HOMO level destabilization and red-shifted optical absorption in the doped state can be achieved through simple derivatization schemes. We demonstrate that a copolymer featuring an alternation of an EDOT unit and a substituted thiophene ring can compete with PEDOT. Moreover, the calculations indicate that the exact layout of the substituents on the thiophene rings can tune the extent of delocalization of the charge carriers in the doped state, and by extension the charge transport properties.

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.
