摘要

A series of 1, 2, 5-oxadiazolo [3, 4-c] pyridines (6, 7, 8 and 10) with thiophene, furan, and benzothiophene rings at the 4 and 7 positions were prepared, in quest of a red fluorescent material useful in OLED devices. Compound (6, 7, 8 and 10) emit fluorescence of orange to red color in solution and in the solid state. 6-Cyano derivatives (6) show a higher quantum yield than the corresponding esters (7), the phenyl derivative (8), and the unsubstituted ...
