Tetra-N-Fused Indolocarbazole Multiple Resonance Emitters Enabling Ultra-Narrowband Pure Green Emission with High Efficiency and Stability
{{output}}
Developing efficient narrowband emitters beyond the blue region remains challenging for indolocarbazole-based multiple resonance (ICz-MR) systems, primarily due to the inherent trade-off between spectral red-shifting and linewidth broadening. To address this, ... ...
