Abstract
Mes 2 B( p- 4,4‘-biphenyl-NPh(1-naphthyl)), (BNPB) a novel luminescent molecule that contains part of the well-known NPB functionality (NPB = N,N ‘ -di-1-naphthyl- N,N ‘ -diphenylbenzidine) and a three-coordinate boron center has been synthesized. BNPB is a bright blue emitter with λ max (emission) = 452 nm and a photoluminescent quantum yield of 95% in solution and 31% in the solid state. BNPB is an amorphous material and forms films readily via either solution casting or vacuum vapor deposition. A single layer EL device A with the device structure of ITO/BNPB/LiF/Al, two double-layer EL devices B and C with the device structure of ITO/NPB/BNPB/Ag for B and ITO/BNPB/Alq 3 /LiF/Al for C, and a triple-layer device D with the structure of ITO/NPB/BNPB/Alq 3 /LiF/Al have been fabricated and their performance has been evaluated. Device A produces a weak blue electroluminescence (EL). Device B produces a bright blue EL, identical to that of device A . Device C produces a green EL, typical of Alq 3 . Device D produces a broadband whitish-blue EL attributable to dual emission from the BNPB zone and the Alq 3 zone. Devices A − D demonstrate that BNPB is capable of transporting both holes and electrons in addition to being a blue emitter for EL devices.

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 it
