- Abstract
- 2,3-Dicyanopyrazine were designed and synthesized via the Knoevenagel condensation of reaction 2,3-dicyano-5-methylpyrazines with 4-(diphenylamino) benzaldehyde. Their structure was characterized by H-1-NMR and FT-IR and elemental analysis. The electroluminescent (EL) performance of multi-layered organic light-emitting devices (OLEDs) fabricated with compound 3a as the emitting layer achieved a current efficiency of 1.57 cd/A with green region CIE coordinates of (0.37, 0.51) and 3b achieved a current efficiency of 0.238 cd/A with red region CIE coordinates of (0.54, 0.42).
