Novel pyridine-containing compounds were synthesized and their properties were studied. Organic EL devices using these compounds as electron-transporting layer were fabricated. It is demonstrated that these compounds are useful for organic light-emitting diodes (OLED) and solid state lighting technology in favor of energy-saving and environmental protection fields.
Alcohol-soluble oxadiazole-based compound as electron-transporting layer in solution-processed OLEDs shows much improved efficiency compared to control devices.
