Abstract
Difluoroboron ß-diketonates (BF2bdks) have impressive optical properties in both solution and the solid state. In particular, both fluorescence and room-temperature phosphorescence are present when the dyes are confined to a rigid matrix, such as poly(lactic acid) (PLA). To expand the current knowledge and colour range capabilities of this unique type of multi-emitting chromophore, a series of thienyl-substituted BF2bdk complexes have been synthesized. The photophysical properties were investigated in dichloromethane solution and in the solid state as dye/PLA blends. By varying donor ability, i.e. methyl, phenyl, methoxy, and thienyl substituents, and by changing the dye loading in the PLA media (0.1–10 % dye loading) red-shifted emission was achieved, which is important for biological imaging applications. In dilute CH2Cl2 solution, complexes exhibited absorptions ranging from 350 to 420 nm, solid-state fluorescence in PLA ranging from 390 to 500 nm, and oxygen sensitive phosphorescence ranging from 540 to 585 nm in PLA blends. Promising candidates as dye/PLA blends serve as models for dye–polymer conjugates for application as biological oxygen nanoprobes.

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
