Abstract
Hyperbranched polycarbosilane-g-β-cyclodextrin(β-CD)polymer brushes based on carbosilane core were synthesized.At first,hyperbranched polycarbosilanes(HBP)with carbosilane cores of 3 to 5 generations were prepared via hydrosilylation addition and pseudo-one-step using methyldiallylsilane as monomer(AB_2)and 1,2-bis(diallyl(methyl)silyl)ethane as core(B_4),respectively.Then,HBP was modified by 1,1,3,3-tetrmethyldisiloxane,allyl alcohol and chloroacetyl chloride for obtaining hyperbranched polycarbosilanes carrying chloride atoms(HBP-Cl).It may which act as a macroinitiator for further polymerization of a hyperbranched polymer with functional arms.For this purpose,HBP-g-poly(N,N-dimethylaminoethyl methacrylate)(PDMA)with different arm length was synthesized by atom transfer radical polymerization(ATRP).Finally,HBP-g-PDMA-β-CD with functional polymer brushes was obtianed by immobilization of Mono-6-I-β-CD onto PDMA chains.Their macromolecular structures were characterized by FTIR,1H-NMR,13C-NMR and 29Si-NMR.In addtion,the macromolecular architecture of HBP-g-PDMA-β-CD,including the inner HBP structure with carbosilane core and the exterior PDMAEMA layer,was confirmed by SEC/MALLS and particle size analyses.Besides,it was found that the amount of β-CD content incorporating onto PDMA segments can also be regulated by changing reaction time.

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
