A π-extended benzothiadiazole derivative for a high-efficiency TADF-sensitized fluorescent organic light-emitting diode
- Key Words:
- Abstract:A new fluorescent emitter based on pi-extended benzothiadiazole was synthesized. The emitter exhibited a large molar extinction coefficient, a high quantum yield of 98% and a large radiative decay rate of 10(8) s(-1). Moreover, the obtained TADF-sensitized fluorescent OLED displayed excellent device performance with a high EQE(max) of 14.3%.
