The recognition and sensing of anions by a novel phenanthroline-bridged diamide
Bibliographic record
Abstract
A novel neutral anion recognition receptor 1 with the additional capability of selectively sensing anionic guest species has been synthesized and examined for its anion-binding abilities by UV–vis absorption spectroscopy. The results of nonlinear curve fitting and Job plot indicate that 1 forms 1:1 stoichiometric complexes with fluoride, chloride, bromide, iodide, and acetate, respectively. Their UV–vis absorption spectra in DMSO indicate the presence of anions such as F – , Cl – , Br – , I – , and AcO – with high affinity ability and selectivity toward F – , and also show dramatic colour changes from colourless to yellow in the presence of TBAX (1× 10 –5 mol/L, X= F – , Cl – , Br – , I – , and AcO – ). Receptor 1 has almost no affinity abilities for H 2 PO 4 – and OH – . Key words: phenanthroline-bridged diamide, synthesis, UV–vis spectrum, anion recognition.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
