Key Points

To explore a strategy for constructing high-performance narrowband emitters using a boron-locked diaza-octagon framework.
Utilized a diaza-octagon core combined with a boron-nitrogen (BN) framework.
Evaluated the efficiency and performance across various doping concentrations.
Assessed molecular packing effects on emitting properties.
Achieved high efficiency maintained at 10 wt% doping concentration.
Demonstrated significant suppression of molecular packing with the 8NN matrix.
Highlighted how the unique structure boosts performance of narrowband emitters.

Abstract

luminance. Notably, such high efficiency is well maintained even at a high doping concentration of 10 wt%, owing to suppressed molecular packing induced by the 8NN matrix. These results highlight a mutual modification strategy that exploits the complementary strengths of the diaza-octagon core and BN framework for high-performance narrowband emitters.
