A new family of deep‐blue thermally activated delayed fluorescence (TADF) emitters based on donor‐acceptor architecture was developed. The electronic interaction between donor and acceptor plays the key role in TADF mechanism. Deep‐blue OLEDs fabricated with these TADF emitters achieved high external quantum efficiencies over 19% with CIE coordinates of (0.148, 0.098).
