Pure-blue hyperfluorescence (HF) OLEDs with high-efficiency, narrow-emission and good stability have been demonstrated. The design is based on a two-unit stacked tandem HF-OLED with an improved singlet-excited energy transfer process from a sky-blue TADF assistant dopant to a pure-blue terminal emitter.
