Leveraging quinoxaline functionalization for the design of efficient orange/red thermally activated delayed fluorescence emitters
A novel functionalization approach of quinoxaline has been unveiled to develop orange/red thermally activated delayed fluorescence (TADF) emitters by modifying the core with three carbazole donors and one or three cyano acceptors. The resulting functionalized TADF emitters demonstrated orange and red emission with promising TADF properties. An organic light-emitting diode fabricated using the orange emitter demonstrated high external quantum efficiency of 18.4%.
