Front Cover: Asymmetric Spirobiacridine‐based Delayed Fluorescence Emitters for High‐performance Organic Light‐Emitting Devices (Chem. Eur. J. 42/2021)

Abstract

Horizontally oriented thermally activated delayed fluorescent (TADF) emitters realizing high‐performance sky‐blue organic light‐emitting devices (OLEDs) are reported in this work. The cover image represents that triphenyltriazine‐based TADF emitters maximize the potential of sky‐blue TADF OLEDs. The small structural differences in acceptor units makes a significant differences to device performance. More information can be found in the Full Paper by H. Sasabe, J. Kido et al.
