Abstract

fetched live from OpenAlex

Single-molecule spectroscopy is used to gain insights into the click chemistry reaction photocatalyzed by copper. We show that Cu x O@Nb 2 O 5 catalysts can act as truly heterogeneous photocatalysts and that the amine plays an important role in the complexation between the alkyne and the copper active site on the catalyst surface. For complex reactions occurring in the subnanomolar range, preassociation can be essential and cocatalysts (such as amines here) may play an enabling role facilitating the reagents “reunion” and prolonging the time available for reaction. This provides a rational analysis of the amine role in heterogeneous photocatalytic click chemistry.

Full frame distilled prediction

Teacher imitation

Not 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.
