摘要
通过联苯甲酰与氨基的缩合反应合成了联苯喹喔啉,并对其进行了表征,研究了其热性能和电性能。将联苯喹喔啉作为电子传输层,制作了ITO/α-NPD/Alq/DDPQL/LiF/Al有机电致发光器件,其性能在13.5V时最高亮度为12100cd/m2,在13.0V时最大电流效率为4.97cd/A,外部量子效率为1.92%,最低驱动电压为3.5V。表明该化合物具备优良的电子传输性能。
Diphenylquinoxaline was synthesized by condensation reaction with benzil and amino. The thermal and electrical properties of diphenylquinoxaline were measured as well. Organic electroluminescent devices using di- phenylquinoxaline as electron-transporting layer was fabricated. The structure of the organic electroluminescent devices is ITO/α-NPD/Alq/DDPQL/LiF/AI. The maximum brightness of the electroluminescent （EL） device at voltage of 13.5V is 12100cd/m2, the maximum current efficiency at voltage of 13.0V is 4.97cd/A, the external quantum efficiency is 1.92%, and the lowest drive-voltage is 3.5V. The result indicates that the compounds are useful as electron-transporting materials in organic electroluminescent devices.
