Efficient delayed fluorescence via triplet–triplet annihilation for deep-blue electroluminescence

Abstract

Four 2-(styryl)triphenylene derivatives (TSs) were synthesized for deep-blue dopant materials. By using a pyrene-containing compound, DMPPP, as the host, the TS-doped devices exhibited significant delayed fluorescence via triplet–triplet annihilation, providing the highest quantum efficiency of 10.2% and a current efficiency of 12.3 cd A−1.
