Abstract

fetched live from OpenAlex

Abstract A significant and reversible size change (up to 80 nm, representing 100 % increase in diameter, i. e. “breathing”) of polymeric micelles of poly(styrene)‐ block ‐poly(3‐(4‐vinylpyridin‐1‐ium‐1‐yl)propane‐1‐sulfonate) (PS‐P4VP‐zwitter) was observed during phototriggered loading and release of spiropyran. The breathing (i. e. “inhaling/exhaling” of the small molecules by the micelles) could be controlled by switching the wavelength of the light used. Spiropyran, which was converted into the zwitterionic merocyanine by UV light, was readily diffused and incorporated into the zwitterionic micelle cores, thus causing the micelles to expand. At the same time, the merocyanine was stabilized by the polyzwitterionic core of the micelles. To the best of our knowledge, this is the first report of a supramolecular and reversibly photoloadable system that can be converted from a thermodynamically stable self‐assembled equilibrium system into a dynamic, self‐assembled system that is sustained by illumination.

Full frame distilled prediction

Teacher imitation

Not 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.
