Judicious Use of Chalcogens in Multiresonant Thermally Activated Delayed Fluorescent Emitters Leads to OLEDs with Efficiencies Exceeding 36% and Showing Mild Efficiency Roll-Off
{{output}}
Strategies that produce OLEDs that simultaneously achieve outstanding electroluminescence efficiency, small efficiency roll-off, good stability, and high color purity remain in strong demand. Herein, we report how judicious decoration of a benzochalcogenophene... ...
