In this study, pyrido[2,3-b]pyrazine emitters enhance OLED efficiency, suggesting potential for improved display technologies.
The strategic use of carbazole or phenothiazine donors in pyrido[2,3- b ] pyrazine emitters governs thermal stability and horizontal molecular orientation, enabling high-performance TADF-based OLEDs with external quantum efficiencies up to 21.3%.
