A series of terpyridine/acridine conjugates exhibits strong blue‐to‐green emission and thermally activated delayed fluorescence (TADF) character in the solid state. An organic light‐emitting device with a green emissive terpyridine/acridine conjugate showed an external quantum efficiency of approximately 25%, a power efficiency of over 80 lm W −1 , and an exceptionally low‐efficiency roll‐off.
