吡啶肼类衍生物在有机电致发光器件中的应用

Organic electroluminescent devices using hydrazine compounds

有机电致发光材料的电子传输材料研究远落后于该领域的其他材料,需要开发出新型的电子传输材料,提高电子传输效率,改善器件性能。以合成的Pybispy和Pybisqu作为电子传输材料,制作了结构为玻璃基板/ITO阳极/空穴传输层/发光层/电子传输层/电子注入层/铝电极的有机电致发光器件,探讨了它们在有机电致发光器件中的性能,Pybispy和Pybisqu作为电子传输材料器件的最大发光亮度分别达到了218和5980cd/m2。结果显示该系列化合物具有电子传输性能,可应用于有机电致发光器件中的电子传输材料。

The study of electron-transporting materials is far behind that of the other organic electroluminescent materials. There arises the necessity of synthesizing novel electron-transporting materials to enhance transporting efficiency and promote properties of devices. Organic electroluminescent devices using hydrazine compounds as the electron transport layer were fabricated. 2, 6-diacetylpyridine bis （2- pyridylhydrazine） （ Pybispy ） and 2, 6-diacetylpyridine his （ 2-quinoldylhydrazine ） （ Pybisqu ） were found to be electron-transporting, and devices with a structure of glass substrate/ITO/ot-NPD/Alq/Pybispy, Pybisqu/LiF/A1 exhibited green electroluminescence from the Alq layer. The maximum luminance of 218 and 5 980 cd/m^2 was observed respectively.
