dc.description.abstractA novel series of D-A-D type conjugated dyes (Py-CyP1-7) centred on a strongly electron-withdrawing cyanopyridone scaffold (A) linked to highly electron-donating pyrene unit (D) and varied auxiliary donors (D) were designed and synthesized, for applications in green organic light-emitting diodes (OLEDs). All the hybrids were systematically subjected to theoretical, optical, electrochemical, and thermal studies to validate their efficiency in behaving as green emitters. Finally, we employed the dyes as sole and dopant emitters in OLEDs. The OLED with 3 wt % Py-CyP4 in the CBP host shows maximum efficiencies of 14.38 cd A−1, 12.04 lm W−1, and 5.91%. © 2023
