Paper Title:
Synthesis and Properties of Diphenylquinoxaline as Electron-Transporting Materials
  Abstract

Bis-(2,3-diphenylquinoxaline) (DDPQL) has been synthesized by condensation reaction with 3,3'-diaminobenzidine and benzil. The thermal and electrical properties of DDPQL were measured as well. Organic electroluminescent device using DDPQL as electron-transporting layer was fabricated. The structure of the organic electroluminescent device is ITO/α-NPD/ Alq/DDPQL/LiF/Al. The maximum brightness of the electroluminescent device at voltage of 13.5V is 12,100cd/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. This indicates that the compounds are useful as electron-transporting materials in organic electroluminescent devices.
