Two novel evaporation‐ and solution‐process‐feasible thermally activated delayed fluorescence emitters , green‐light‐emission ACRDSO2 and yellow‐light‐emission PXZDSO2, based on a brand‐new electron‐acceptor moiety thianthrene‐9,9′,10,10′‐tetraoxide, are developed for organic light‐emitting diodes. The solution‐processed devices, without any hole‐transport layer, exhibit competitive performance and reduced efficiency roll‐off compared with corresponding vacuum‐deposited devices.
