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 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; both teacher heads agree on what is shown here.
