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

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.
