Amorphous Diblock Copolymers with a High Organometallic Block Volume Fraction: Synthesis, Characterization and Self-Assembly of Polystyrene-<i>block</i>-Poly(ferrocenylethylmethylsilane) in the Bulk State
Bibliographic record
Abstract
The preparation of polystyrene- b -poly(ferrocenylethylmethylsilane) diblock copolymers (PS- b -PFEMS) with a high volume fraction of the organometallic block (ϕ PFEMS = 0.69−0.87) has been achieved via the sequential living anionic polymerization of styrene and ethylmethylsila[1]ferrocenophane. High molecular weights ( M n = 50000 to 250000 g/mol) and narrow molecular weight distributions (PDI = 1.05−1.17) were achieved. As both of the blocks are amorphous, the resulting diblock copolymers undergo predictable self-assembly in the bulk and well-ordered microdomains are reported. The data described complement previous results on analogous block copolymers with a low PFEMS volume fraction and a morphology diagram for PS- b -PFEMS is described.

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.
