Highly simplified blue phosphorescent organic light-emitting diodes incorporating exciplex-forming co-host assisting energy transfer
The exciplex-forming mixed host with doped phosphorescent dye shows potential to realize high performance phosphorescent organic light emitting didoes (PhOLEDs). Herein, we report a novel exciplex-forming co-host architecture by combining N,N,10-triphenyl-10H-spiro[acridine-9,9'-fluoren]-3'...
