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 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 it
