Organometallic Gels: Characterization and Electrochemical Studies of Swellable, Thermally Crosslinked Poly(ferrocenylsilane)s
Bibliographic record
Abstract
Investigations on a series of crosslinked poly(ferrocenylsilane) networks that have been prepared via the ring-opening copolymerization of the silicon-bridged [1]ferrocenophane fcSiMe2 (fc = Fe(η-C5H4)2) with controlled amounts of a spirocyclic [1]ferrocenophane fcSi(CH2)3 are reported. These crosslinked poly(ferrocenylsilane)s have improved thermal stability relative to their linear counterparts. The swelling response 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 swelling measurements in a variety of liquids, it was determined that the best solvents for poly(ferrocenyldimethylsilane) are THF, chloroform, and dichloromethane. The solubility parameter (δ) for the linear homopolymer was found to be 18.7(7) MPa1/2. Reversible electrochemical oxidation of the gel was observed at oxidation potentials greater than 450 mV (vs Ag/AgCl), consistent with the oxidation potential of the linear homopolymer, and an intervalence charge transfer band was detected at 1300 nm for the partially oxidized material.

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.
