Five-Boron Multiple-Resonance TADF Emitter With Accelerated Reverse Intersystem Crossing for High-Performance Narrowband Green OLEDs.
Multiple-resonance thermally activated delayed fluorescence (MR-TADF) emitters are promising candidates for organic light-emitting diodes owing to their narrowband emission and high exciton utilization. While π-conjugated framework expansion has been extensively explored for tuning excited-state properties, five-boron...
