Light-emitting electrochemical cells (LECs) are considered as the next-generation lighting sources as a potential replacement for organic light-emitting diodes (OLEDs). Ionic organic small molecules (SMs) have established the applicability in solid-state lighting, and is seen as a prospective active material for LECs with higher device performance. In this study, we report the design and synthesis of two new green fluorescent light emitting ionic small molecules with triazine acceptor. The synthesized green emitters showed excellent solubility, high luminescence in solution and solid state, high thermal stability, and good film-forming abilities. Thermal stabilities were noted to be very high at 370 and 358 °C for these molecules. The glass transition temperatures were also noted to be very high 120 and 104 °C. These nondoped LEC device exhibited green emission at 505 and 499 nm with Commission Internationale de I’Eclairage coordinates of (0.28, 0.54) and (0.27, 0.52).
