High electron mobility in organic thin films has in general been difficult to achieve. Oxadiazole derivatives are among the most successful electron conducting/hole blocking materials employed in organic light-emitting devices (OLEDs), the aluminum–oxadiazole complex presented here, tris(2-(5-phenyl-1,3,4-oxadiazol-yl)phenonate) aluminum (AlPOP), being no exception. OLEDs based on AlPOP are reported to exhibit a strong blue emission with high external efficiency and brightness and excellent shelf lifetime stability.
