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

ABSTRACT 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‐...

Peripheral Para ‐Chalcogen‐π‐Oxygen Fusion Strategy for High‐Performance Deep‐Blue Narrowband MR‐TADF OLEDs

ABSTRACT Narrowband deep‐blue emitters featuring a targeted emission peak (465 ± 3 nm) and high reverse intersystem crossing (RISC) rate are highly desirable for ultra‐high‐definition displays. Herein, guided by the para ‐chalcogen‐π‐oxygen alignment strategy, two novel derivativ...
