Hg<sup>2+</sup>‐Induced In Situ Generated Radical Cation of (<i>S</i>)‐BINOL‐Based Polymer for Highly Enantioselective Recognition of Phenylalaninol
Bibliographic record
Abstract
Phenylalaninol enantiomers are one of the most important chiral compounds due to its presence in biologically active molecules and pharmaceutical products. In this paper, a novel chiral fluorescence polymer sensor incorporating (S)-BINOL and oligomeric aniline via a nucleophilic addition-elimination reaction is designed and synthesized. Polymer sensor exhibits "turn-off" fluorescence quenching response upon the addition of Hg(2+) , and "turn-on" moderate fluorescence enhancement behavior towards phenylalaninol enantiomers. Meanwhile, this kind of (S)-BINOL-based polymer sensor can exhibit highly selective enantioselective recognition response towards (L)-phenylalaninol upon the addition of Hg(2+) and the value of ef can reach as high as 5.4, which can be attributed to the formation of in situ generated radical cation arisen from oligomeric aniline moiety by Hg(2+) induction.

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.
