Stimuli-Responsive Gels Based on Ring-Opened Polyferrocenes: Synthesis, Characterization, and Electrochemical Studies of Swellable, Thermally Cross-Linked Polyferrocenylsilanes
Bibliographic record
Abstract
A series of crosslinked polyferrocenylsilane networks have been prepared via the copolymerization of the silicon-bridged [1]ferrocenophane, fcSiMe2 (fc = Fe(η -C5H4)2) with controlled amounts of a spirocyclic [1]ferrocenophane fcSi(CH2)3. Thermal analysis revealed that the crosslinked polyferrocenylsilanes have improved thermal stability relative to their linear counterparts. Swellability was investigated as a function of temperature, solvent and crosslink density. As expected, the degree of crosslinking had a dramatic effect on the swelling in various media. From swellability measurements in various solvents, it was determined that the best solvents for poly(ferrocenyldimethylsilane) are THF, chloroform, and dichloromethane. The solubility parameter (δ) for the homopolymer was found to be 18.7(7) MPa1/2. The redox and spectroscopic properties of the gels were investigated using spectroelectrochemistry in an optically transparent thin-layer electrochemistry (OTTLE) cell. Significant oxidation of the gel was evident at oxidation potentials greater than 450 mV (vs Ag/AgCl), consistent with the first oxidation potential of the linear homopolymer.

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.
