Abstract
Supramolecular chemistry, or "chemistry beyond the molecule", is an increasingly important area of modern chemical research. It deals with highly organized structures involving two or more individual molecules held together by intermolecular forces. Supramolecular host-guest inclusion complexes refer to structures in which a smaller "guest" molecule is held within the internal cavity of a larger "host" molecule. Supramolecular systems have widespread practical applications to various areas of chemistry, including catalysis, molecular sensors and chemical separations. In this article, we describe a simple yet striking demonstration of supramolecular host-guest inclusion and fluorescence based on the extraordinarily large observed fluorescence enhancement of the probe ANS by a modified ß-cyclodextrin. The fluorescence enhancement is readily observable by the naked eye. This demonstration is appropriate for an advanced organic or physical chemistry class and requires only a simple hand-held UV lamp as the excitation source.

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 it
