Boosting reverse intersystem crossing by increasing donors in triarylboron/phenoxazine hybrids: TADF emitters for high-performance solution-processed OLEDs

Three triarylboron-based TADF emitters are developed by integrating electron-donating phenoxazine units and electron-accepting triarylboron units. Employing these TADF emitters in the solution-processed organic light-emitting diodes achieves a maximum external quantum efficiency of 13.9% and slight...

Zusammenfassung:Three triarylboron-based TADF emitters are developed by integrating electron-donating phenoxazine units and electron-accepting triarylboron units. Employing these TADF emitters in the solution-processed organic light-emitting diodes achieves a maximum external quantum efficiency of 13.9% and slight efficiency roll-off.
