OLED device and application evidence (1)
Device EQE, electroluminescence and lifetime refer to specified devices and operating conditions, not intrinsic constants of the emitter.
Device / application record 1 — As a 10 wt% mCP sensitizer with 1 wt% ν-DABNA terminal emitter, main Fig. 4e reports HF EQEmax about 20% versus about 5% AZB-only.

- limitation
- Applies to a specific sensitizer/terminal-emitter co-doped OLED device, not an isolated molecular photophysical property. Device EQE and lifetime depend on full architecture, luminance and host. Direct claims of commercial readiness are not warranted.

DOI 10.1038/s41566-024-01395-1ACRSA/DMAC-TRZ are sensitizers in 10wt% mCBPCN films; AZB-TRZ is sensitizer in 10wt% mCP; ν-DABNA terminal emitter 1wt% in mCBPCN vs mCP gives distinct PLQY. FRET efficiency is pair/film-system property, not intrinsic scalar material property. SI Table S5 vs S6 AZB-TRZ kFRET conflict and SI Table S6 AZB host heading ambiguity remain OPEN.
