Electrochemistry and Spectroelectrochemistry of Strongly Electron-Withdrawing Metallated Octanitrophthalocyanines
Bibliographic record
Abstract
The spectral and electrochemical properties of metallated octanitrophthalocyanines, [M II {(NO 2 ) 8 pc}] where M = Zn, Cu or Co, were studied by electrochemical and spectroelectrochemical methods as well as electronic absorption and magnetic circular dichroism spectroscopy. Aggregation is observed for several species. The octanitrophthalocyanines are easier to reduce and more difficult to oxidize than most other metallophthalocyanines. Indeed, the first ring-localized reduction potential observed with these phthalocyanine species, is the most positive of the metallated, neutral phthalocyanines in the literature. These data are added to existing Hammett free energy relationship database to extend design protocols for substituted metallophthalocyanines. Optical spectra for several redox series are presented and related to the existing literature.

How this classification was reachedexpand
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.
