Synthesis, Characterization, and AFM Studies of Dendronized Polyferrocenylsilanes
Bibliographic record
Abstract
Dendronized polyferrocenylsilanes were synthesized by a substitution reaction of reactive poly(ferrocenylchloromethylsilane) with monodendrons with a focal hydroxy group. The resulting dendronized polymers were studied by 1 H NMR, differential scanning calorimetry (DSC), and polarized optical microscopy (POM). To facilitate the direct visualization of single polymer chains by atomic force microscopy (AFM), an interaction chromatography technique (IC) was used to fractionate the polydisperse polymers to separate the high molecular weight dendronized PFSs. AFM studies of the fractionated high molecular weight PFSs revealed a spherical cocoon for the single chains of the dendronized polymer as well as elongated single-chain structures. The cocoon of the dendronized PFS could be interesting as a unimolecular micelle with the transition-metal-rich core which is isolated by the dense outer layer of the dendrons.

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.
