Abstract:
We report a design strategy for highly efficient, narrowband pure-organic green emitters that combines a contorted double-boron-embedded skeleton with peripheral cyano modification. Non-sensitized OLEDs incorporating this design deliver a maximum external quantum efficiency of 36.5% and a peak power efficiency of 197.7 lm W-1 with low efficiency roll-off.
