Abstract

Abstract : Thermally activated delayed fluorescence (TADF) emitters have been studied thoroughly; however, the development of red/near‐infrared TADF emitters has lagged behind that of green and blue emitters. In their Research Article on page 14660 ff., K. Wang, C.‐S. Lee, X.‐H. Zhang, and co‐workers present two novel red TADF emitters. Organic light‐emitting diodes based on these emitters achieved near 100 % exciton utilization.
