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 — This is the 1 wt% terminal emitter in hyperfluorescence systems; source-linked system device metrics depend on particular ACRSA/DMAC-TRZ/AZB-TRZ sensitizer, host and full stack.

Key requirements for ultraefficient sensitization in hyperfluorescence organic light-emitting diodes

DOI 10.1038/s41566-024-01395-1

Source ID: SRC-STAVROU-2024-NATPHOT

ACRSA/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 k_FRET conflict and SI Table S₆ AZB host heading ambiguity remain OPEN.
