Cover Feature: Radical Complexes of Nickel(II)/Copper(II) and Redox Non‐innocent MB‐DIPY Ligands: Unusual Stability and Strong Near‐Infrared Absorption at <i>λ</i><sub>max</sub> ∼1300 nm (Chem. Eur. J. 41/2022)
Bibliographic record
Abstract
The preparation of radicals with intense and redox-switchable absorption beyond 1000 nm is a long-standing challenge in the chemistry of functional dyes. We now report a series of unprecedented stable neutral nickel(II) and copper(II) complexes of “Manitoba-dipyrromethenes” (MB-DIPYs) in which the organic chromophore is present in the anion–radical state. The new stable radicals have an intense absorption at λmax∼1300 nm and can be either oxidized to a regular [MII(MB-DIPY)]+ (M = Cu or Ni) or reduced to [MII(MB-DIPY)]− compounds. More information can be found in the Research Article by F. Thomas, J. van Lierop, V. N. Nemykin, and co-workers (DOI: 10.1002/chem.202201181).

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.
