para-Boron Dendritic Modulation of MR-TADF Emitters Enables High-Efficiency Narrowband Solution-Processed OLEDs.
The rigid planar structure of multi-resonance thermally activated delayed fluorescence (MR-TADF) emitters delivers narrowband emission with high color purity but also induces spectral broadening and poor solution processability, hindering their application in solution-processed OLEDs. Herein, we develop a dendritic fun...
