Thin-Layer Electrochemistry of 1,3-Diferrocenyl-2-buten-1-one: Direct Correlation between Driving Force and Liquid/Liquid Interfacial Electron Transfer Rates
Bibliographic record
Abstract
The cyclic voltammetric behavior of 1,3-diferrocenyl-2-buten-1-one (abbreviated as DFcB ), a novel molecule with two electrochemically nonequivalent redox centers, was investigated by the thin-layer method, a simple protocol reported recently for studying electron transfer reactions at liquid/liquid interfaces. The bimolecular rate constants for the two-step electron transfer reactions between DFcB in the organic phase and [Fe(CN) 6 ] 4- located in the adjacent aqueous phase were obtained simultaneously at a single interface. The observed clear dependence of the rate constants on the overall driving force (dominated by the apparent formal potentials of the ferrocenyl groups in DFcB) is consistent with previous studies and qualitatively in agreement with the conventional Butler−Volmer treatment. The results demonstrate the feasibility of using molecules containing multiple redox centers to study the correlation between the thermodynamic driving force and electron transfer kinetics at liquid/liquid interfaces.

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.
