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).

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.
