Invited for the cover of this issue is Hisahiro Sasabe, Junji Kido and co‐workers at Yamagata University in Japan. This image depicts that the chemical structure of the acceptor is one of the most important keys to maximize the potential of triazine/acridine‐based thermally activated delayed fluorescence (TADF) emitters realizing high external quantum efficiency (EQE) of over 30%.
