A Bisamide Ruthenium Polypyridyl Complex as a Robust and Efficient Photosensitizer for Hydrogen Production
Bibliographic record
Abstract
Abstract A photosensitizer based on a ruthenium complex of a bisamide‐polypyridyl ligand gives rise to a large improvement in photocatalytic stability, rate of activity, and efficiency in photocatalytic H 2 production compared to [Ru(bpy) 3 ] 2+ (bpy=2,2′‐bpyridine). The bisamide ruthenium polypyridyl complex combined with a cobaltoxime‐based photocatalyst was found to be highly efficient under blue‐light (turnover number (TON)=7800) and green‐light irradiation (TON=7200) whereas [Ru(bpy) 3 ] 2+ was significantly less effective with a TON of 2600 and 1100, respectively. The greatest improvement was under red‐light‐emitting diodes, with bisamide ruthenium polypyridyl complex and cobaltoxime exhibiting a TON of 4200 compared to [Ru(bpy) 3 ] 2+ and cobaltoxime at a TON of only 71.

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.
