Abstract

Abstract : Extremely efficient blue organic electroluminescence with external quantum efficiency of 37% with a conventional planar device structure is reported by K.‐T. Wong, C.‐C. Wu, and co‐workers on page 6976. Such a high efficiency is realized by thermally activated delayed fluorescence emitters based on spiroacridine–triazine hybrids, which simultaneously possess nearly 100% photoluminescence quantum yield and strongly horizontally oriented emitting dipoles.
