Abstract

AbstractDuring the past decade, the discovery of thermally activated delayed fluorescence (TADF) materials has significantly boosted the development of organic light‐emitting diode (OLED) technology. Compared with small‐molecule and polymeric TADF materials, TADF dendrimers have emerged as promising emitters for solution‐processed OLEDs because they have the integrated advantages of TADF small molecules and polymers in achieving high efficiency, excellent solution processability, and precise molecular structures. In recent years, TADF dendrimers have experienced important advances in molecular design, mechanism exploration and device performance. Herein, we present a comprehensive review of solution‐processable TADF dendrimers, mainly focusing on their molecular design principles and structure–property correlations. The advanced device performances of these dendrimers are also summarized. Finally, we proposed the prospects and challenges on the development of TADF dendrimers.
