Molecular Design Opening Multiple Charge Transfer Pathways in Oxygen‐Bridged Boron Emitters for High‐Efficiency Pure Violet Organic Light‐Emitting Diodes
Researchers have engineered two oxygen‑bridged boron thermally activated delayed fluorescence (TADF) emitters—BOID‑Cz‑Si and BOBF‑Cz‑Si—by integrating indole and benzofuran donor units. The compounds deliver pure violet light near 400 nm with a narrow 25 nm full width at half‑maximum and photoluminescence quantum yields up to 95%. In OLED devices, BOID‑Cz‑Si emits at 420 nm and reaches a 22.7% external quantum efficiency, one of the highest reported for violet emitters. The design leverages combined short‑ and long‑range charge‑transfer within a multiple‑resonance framework while suppressing intermolecular quenching.
