Linear and branched electroactive polymers based on ethylenedioxythiophene–triarylamine conjugates
Bibliographic record
Abstract
Triphenylamines with one, two, or three 3,4-ethylenedioxythiophene (EDOT) substituents attached to the para-phenyl carbons have been prepared via metal-catalyzed cross-coupling reactions. The amines with two or three EDOTs (compounds 4 and 3, respectively) can be oxidatively electropolymerized (via intermolecular coupling between two EDOT groups at their respective α-carbon atoms) to afford stable, linear and cross-linked polymers, respectively. The linear polymer (poly-4) exhibits two resolved, reversible oxidation waves corresponding to the oxidation of the amine and EDOT centers. These two oxidation processes occur at the same potential in cross-linked poly-3 giving rise to one broad, reversible oxidation wave. The observation of redox processes associated with the EDOT-based chromophores contrasts the properties of related (non-EDOT-containing) polymers for which the thiophene backbone serves only as a conjugated ‘linker’. These polymers are highly stable to electrochemical oxidation and can be electrochemically cycled hundreds of times with no detectable decomposition; color changes accompany the redox processes, interconverting between reduced (yellow) and oxidized (green–blue) forms.

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.
