Effect of Triarylamine Structure on the Photoinduced Electron Transfer to Boron Subphthalocyanine
Bibliographic record
Abstract
The photoinduced electron transfer (PET) reaction between a phenoxy-boronsubphthalocyanine derivative and a series of triarylamine electron donors was investigated. A series of triarylamines ranging in oxidation potentials and number of redox centers were prepared to study the effect of triarylamine structure on the photoinduced electron transfer (PET) reaction. In the case of multiple nitrogen centers, the triarylamines were dendritic in nature and were synthesized by a convergent strategy relying on successive C–N coupling and thermolytic deprotection steps. The efficiency of the PET reaction was found to be exponentially dependent on the oxidation potential of the triarylamine beyond a certain threshold. The free-energy change of the PET reaction was estimated using the Rehm–Weller equation, and this framework could be used to adequately explain the observed behavior of the system. We have concluded that the specific structure of the triarylamine is not important in the PET reaction and that efficiency of electron transfer is almost solely dictated by the oxidation potential of the triarylamine donor.

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.
