Synthesis and Solution Self‐Assembly of Polyisoprene‐<i>block</i>‐poly(ferrocenylmethylsilane): A Diblock Copolymer with an Atactic but Semicrystalline Core‐Forming Metalloblock
Bibliographic record
Abstract
Polyisoprene‐ block ‐poly(ferrocenylmethylsilane) (PI‐ b ‐PFMS) copolymers, containing the atactic but semicrystalline PFMS block, have been prepared by sequential anionic polymerization of isoprene and methyl[1]silaferrocenophane. The reaction to form the metalloblock is not living in nature, but still enabled three block copolymers to be prepared (PI 35 ‐ b ‐PFMS 5 , PI 200 ‐ b ‐PFMS 10 , and PI 247 ‐ b ‐PFMS 23 ) with relative narrow molar mass distributions (polydispersity < 1.3). The self‐assembly of all three materials was studied in PI selective n ‐alkanes and found to afford lenticular platelets, tapered cylindrical micelles, and regular cylinders, as the length of the PFMS block increased. PI 200 ‐ b ‐PFMS 10 micelles could be increased in length by self‐seeding a sample of short micelles at temperatures of 90 °C and above; however, this process also resulted in an increase in width. Addition of a solution of PI 247 ‐ b ‐PFMS 23 copolymer to preformed seed micelles also resulted in an increase in length, although growth is not linearly related to the amount of copolymer added beyond ≈600 nm. image

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.
