Electrochemical Properties of a Pyridine-Tunable Trisferrocenylborane
Bibliographic record
Abstract
Non-aqueous redox flow batteries (NARFBs) offer promising solutions for sustainable and long-term energy storage. Herein, trisferrocenylborane (BFc 3; Fc = ferrocene, Cp 2 Fe, and Cp = C 5 H 5 – ) is examined for its potential role as a tunable anolyte for use in NARFBs. BFc 3 contains three readily oxidized ferrocene units along with a mediating borane that hosts an empty p orbital, allowing tuned access to specific redox properties as a function of nucleophile choice. The electrochemical behavior (cyclic voltammetry, charging/discharging cycles, etc.) of BFc 3 are accordingly examined in the presence of a series of 4-R-substituted pyridines (R = NMe 2, NH 2, t Bu, Et, or I), with a range of nitrogen donor strengths. These adducts produce a linear correlation that relates E 1/2 to the para -substituent constant (σ p ), showing a tunability of 200–300 mV based on donor choice alone; solvent effects using tetrahydrofuran, acetonitrile, and dichloromethane are additionally discussed.

How this classification was reachedexpand
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.
