Abstract
Association constants between diphenylborinic acid and representative analytes capable of reversible two-point covalent binding (diols, catechols, and hydroxy acids) were determined using an indicator-displacement assay. Unlike boronic acids, which have been studied in great detail as receptors for diols and related compounds, borinic acids have effectively been ignored as candidates for such applications. The results of this study indicate that diphenylborinic acid displays high affinity for certain analytes of this type in aqueous solution. Of particular interest are differences between the selectivity of the borinic acid and that of a boronic acid of similar pKa towards the series of analytes studied: the borinic acid displays an unusually high level of discrimination for catechols over carbohydrates. The distinct selectivity observed, and the unique opportunities for steric and electronic tuning of diarylborinic acids, suggest that these compounds hold significant potential for applications in aqueous-phase molecular recognition.

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 it
