Fluorinated Phenoxy Boron Subphthalocyanines in Organic Light-Emitting Diodes
Bibliographic record
Abstract
Three fluorinated BsubPc s have been synthesized and characterized. Crystals suitable for XRD were grown by slow vapor diffusion and sublimation. Analysis of their crystal structures revealed a dimeric association of BsubPc units for F 5 BsubPc and columnar packing for F 12 BsubPc and F 17 BsubPc . Cyclic volatmmetry (CV) was used to probe the frontier orbital energy levels of these compounds in both dichloromethane and acetonitrile solution; however, only F 5 BsubPc underwent oxidative events, whereas all three compounds underwent reductive events. A −362 and −37 mV shift in the reductive peak potential was observed for peripheral and axial fluorination, respectively, as measured by cyclic voltammetry. Solution UV−vis absorption and photoluminescence spectra were measured in dichloromethane. All three compounds demonstrated air-stable n -type conductivity in single-carrier devices and extremely narrow orange EL emission with a fwhm of only ∼30 nm. F 5 BsubPc showed a maximum luminescence of 122 cd/m 2 at 8 V, with a maximum current efficiency of 0.03 cd/A, whereas the devices fabricated from F 12 BsubPc and F 17 BsubPc produced luminescence with a maximum value of <1 cd/m 2 .

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.
