A new fluorescent emitter based on π-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%.
