Abstract
Photophysical measurements of 6-methylcoumarin (1) encapsulated within cucurbit[8]uril (CB[8]) indicate a pronounced red shift in the fluorescence maximum with an increase in the emission quantum yield and fluorescence lifetime. In addition, at 77 K, there is observable phosphorescence upon encapsulation within CB[8]. The photophysical measurements add credibility to our previously proposed dynamic nature of the CB–coumarin complex in solution. The dynamic nature of the CB[8]–coumarin host–guest complex in water is critical to a CB acting as a supramolecular catalytic nanoreaction vessel to facilitate the photodimerization of coumarins leading to syn dimers.

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
