In their article number 1801282 , Hisahiro Sasabe, Junji Kido and co‐workers first demonstrate sky‐blue thermally activated delayed fluorescent (TADF) emitters based on imidazole derivatives. The cover image pictorially represents the finding that a fused imidazole‐based TADF emitter enables the realization of high‐efficiency sky‐blue organic light‐emitting devices.
