Electron Transport in Bithiophene−Bithiazole Based Metallopolymers
Bibliographic record
Abstract
Electron transport in electrochemically polymerized films of Ru(5,5‘-bis(2-thienyl)-2,2‘-bithiazole)(bpy) 2 2+ and Os(5,5‘-bis(2-thienyl)-2,2‘-bithiazole)(bpy) 2 2+ (bpy = 2,2‘-bipyridine) has been investigated by electrochemical impedance spectroscopy. Electron diffusion coefficients for the M(III/II) mixed valence states are significantly higher than for similar nonconjugated polymers, indicating that the conjugated backbone facilitates electron transport between metal sites. The operation of a hole-type superexchange mechanism is proposed on the basis of the observations that electron transport is faster for the Ru polymer than for the Os polymer and is faster than for the electron-deficient polybenzimidazole based polymers previously investigated.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
