Web13 de dez. de 2024 · Abstract Thermally activated delayed fluorescence (TADF) materials based on multiple resonance (MR) effect exhibit enormous potentials in organic light-emitting diodes (OLEDs) with high color purity due to their intrinsically narrow emission. However, most of MR-TADF emitters are limited to the boron-nitrogen-based rigid skeleton.
