Advanced Optical Materials, EarlyView.Blue organic light‐emitting diodes (OLEDs) comprising triplet‐harvesting emitters require the use of high‐triplet‐energy hosts and blocking layers to confine the triplet excitons to the emitter. Here, we present efficient single‐layer blue hyperfluorescent OLEDs comprising solely of a matrix‐free emissive layer between two charge‐injecting electrodes ...
