Effect of Increasing Ligand Conjugation in Cu(I) Photosensitizers on NiO Semiconductor Surfaces
Bibliographic record
Abstract
Dye-sensitized photoelectrochemical cells may be used as heterogeneous catalysts for fuel-forming and redox reactions. We describe here the synthesis, characterization, and study of ground and excited state properties of three Cu(I) complexes involving three different ligands with varying electron accepting capacities. Femtosecond and nanosecond transient absorption studies confirm the formation of a singly reduced acceptor ligand after photoexcitation of the Cu(I) centre. These complexes are surface anchored onto nanostructured NiO on conductive fluorine-doped tin oxide on glass to fabricate photocathodes. It was found that even though the ligands with increasing conjugation have effects on the formation of the final excited state in solution, they exhibit similar photocurrents upon white light illumination suggesting hole transfer to NiO happening in advance of the formation of the final excited state.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
