Temperature-, Light-, and Host-Molecule-Responsive Polymers with UCST Behavior for Aqueous Sensing Applications
Bibliographic record
Abstract
A light-sensitive moiety, azobenzene, is incorporated into polyacrylamide (PAM) to yield copolymers with upper critical solution temperatures (UCST) in aqueous solutions. The thermoresponsiveness of the copolymers can be tuned not only by light irradiation, which causes the transition between the trans - and cis -forms of the azobenzene, but also by addition of α-cyclodextrin (α-CD), which preferentially complexes with the trans -form of azobenzene. The UCST transition is a combined effect of hydrogen bonding between the amide groups of the PAM chains and the hydrophobic interaction between azobenzene units, the latter of which can be influenced by the photoisomerization of azobenzene and the host–guest interaction between azobenzene and α-CD. The strategy of incorporating switchable hydrophobicity may inspire designs of UCST polymers, which may have potential applications as drug delivery devices and catalyst carriers.

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.
