Description
Summary:The subclass of multi resonant thermally activated delayed fluorescent emitters ( MR-TADF ) containing boron atoms has garnered significant attention in the field of organic light emitting diode (OLED) research. Among boron-based MR-TADF emitters, double boron-embedded MR-TADF ( DB-MR-TADF ) emitters show excellent electroluminescence performances with high photoluminescence quantum yields, narrow band emission, and beneficially small singlet-triplet energy levels in all the full-color gamut regions. This article reviews recent progress in DB-MR-TADF emitters, with particular attention to molecular design concepts, synthetic routes, optoelectronic properties, and OLED performance, giving future prospects for real-world applications. Thermally activated delayed fluorescent (TADF) emitters are inexpensive and versatile materials for organic light emitting diodes (OLEDs) covering all colour regions. Here, the authors review double boron embedded multi resonant TADF emitters with particular attention to molecular design concepts, synthetic routes, optoelectronic properties, and OLED performance, providing future prospects for display applications.
