A series of novel phenanthroline derivatives (Phens) have been synthesized and their application to organic light-emitting devices (OLEDs) as an electron-transport layer was investigated. The OLEDs with a structure of ITO/α-NPD/Alq3/Phen/LiF/Al exhibited remarkable performances and lower operating voltages compared to Alq3-based device, indicating that Phens posses favorable electron-transport properties.
我们合成了一系列新型菲罗啉衍生物(Phens),并研究了它们作为电子传输层在有机发光器件(OLED)中的应用。与基于 Alq3 的器件相比,ITO/α-NPD/Alq3/Phen/LiF/Al 结构的 OLED 表现出卓越的性能和更低的工作电压,这表明 Phens 具有良好的电子传输特性。
