Dibenzophenazine-Fused Heterocyclic Luminophores: Decoding High-Performance Organic Light-Emitting Diodes Based on Long-Wavelength Exciplex.
Developing highly efficient long-wavelength exciplexes remains a challenge due to the constraints of the energy gap law and severe non-radiative loss. In this study, we report a rigid nitrogen-rich donor, 3N, featuring the first fused framework constructed from two anti-aromatic phenazine units. This unique architectur...
