Dibenzophenazine-Fused Heterocyclic Luminophores: Decoding High-Performance Organic Light-Emitting Diodes Based on Long-Wavelength Exciplex

A quasi-planar super-donor (3N) with an elevated highest occupied molecular orbital level enables tight intermolecular stacking. This boosts photoluminescence quantum yields of two exciplex systems to 92% (557 nm) and 78% (604 nm). Consequently, organic light-emitting diodes (OLEDs) achieve maximum external quantum efficiencies of 25.6% (556 nm) and 24.7% (586 nm), showing great potential for long-wavelength exciplexes.
