Abstract
Abstract Materials exhibiting multiple resonance thermally activated delayed fluorescence (MR‐TADF) have attracted attention in organic electronics because of their high photoluminescence quantum yield and narrowband emission. While these superior properties are also desirable for probes for biological imaging, MR‐TADF emitters have yet to be broadly exploited in this field. Here, the MR‐TADF emitter QAO is incorporated into polymer nanoparticles to construct biological imaging probes with narrowband emission and delayed fluorescence. A monomer QAO‐NB is first designed by incorporating a norbornene polymerization handle onto the QAO core, which is then incorporated into a polymer backbone by ring‐opening metathesis polymerization to afford water‐dispersible fluorescent polymer dots, or Pdots. Photophysical characterization confirmed that narrowband emission is preserved in both the polymers and Pdots (λ max = 467–478 nm, FWHM ≤ 50 nm), with a delayed fluorescence lifetime of 455 µs in the Pdots. Multichannel fluorescence imaging studies using comparisons against donor‐acceptor TADF materials underscore the potential of MR‐TADF for the development of narrowband emissive bioimaging probes.

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
