Blue Luminescent Three-Coordinate Organoboron Compounds with a 2,2‘-Dipyridylamino Functional Group
Bibliographic record
Abstract
Two new three-coordinate organoboron compounds tris[p-(2,2'dipyridylamino) phenylduryl]borane (1) and tris[p-(2,2'dipyridylamino)biphenylduryl]borane (2) have been synthesized in good yields by using Pd-catalyzed Suzuki-Miyauya coupling reactions between tri(p-iododuryl)borane and the corresponding boronic acid. Both compounds display bright blue luminescence when irradiated by UV light. The emission band of both compounds is highly solvent-dependent, indicating the presence of a highly polarized excited state. These new boron compounds are stable under air in solution and the solid state, and are capable of binding to metal ions such as Zn(II) via the 2,2'-dipyridylamino chelating sites. The crystal structures of 1 and 2 have been determined.

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.
