Temperature-Responsive Supramolecular Assembly and Morphology of Arborescent Copolymer Micelles with a Solvophilic Core−Solvophobic Shell Structure
Bibliographic record
Abstract
This paper describes the supramolecular assembly of arborescent (dendrigraft) copolymers in solution. The dendritic copolymers remained as unimolecular (nonassociated) micelles in toluene at temperatures above the critical self-assembly temperature (cst) but aggregated into supramolecular structures with a diameter of a few micrometers below the cst. Small-angle neutron scattering (SANS) measurements in toluene revealed that the P2VP shell of the unimolecular micelles was swollen above the cst. The supramolecular aggregates obtained below the cst had a spherical topology and a relatively uniform size according to electron microscopy analysis. The temperature-responsive self-assembly process was fully reversible. The cst varied with the copolymer concentration and shifted to higher temperatures as the length of the P2VP chains in the shell increased. The self-assembly mechanism reported provides a path to new types of “smart” supramolecular structures.

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.
