High-Efficiency Deep-Blue Narrowband Electroluminescence via Multi-Sensitization Using a D-meta-π-A Sensitizing Host.
The strategic integration of thermally activated delayed fluorescence (TADF) sensitizers has emerged as a critical approach for triplet recycling in organic light-emitting diodes (OLEDs) with multiple resonance (MR) emitters. However, conventional single-sensitizer systems are frequently limited by slow exciton utiliza...
