• By simple modification of the functional groups on the donor unit, the thermally activated delayed fluorescence (TADF) properties of emitters can easily be manipulated. A series of deep blue to blue emissive TADF derivatives is developed, capable of deep‐blue emissions from 403 to 460 nm in toluene. Deep‐blue organic light‐emitting diodes (OLEDs) based on this series of TADF emitters are fabricated, resulting in an electroluminescence peak at 428 nm and a high external quantum efficiency of up to 10.3%. One deep‐blue OLED has achieved the commission internationale de l'eclairage (CIE) coordinates of (0.156, 0.063), which is among the best reported TADF performances for deep‐blue OLEDs with CIEy < 0.07. A series of deep‐blue to blue emissive TADF derivatives is developed, by which deep‐blue emissions from 403 to 460 nm in toluene are achieved. Deep‐blue OLEDs based on this series of TADF emitters are fabricated, exhibiting an electroluminescence peak at 428 nm and a high external quantum efficiency of up to 10.3%.
