摘要:
Azatriphenylene derivatives and their use in the electron-transporting layer of an electroluminescent device that comprises an anode, a spaced-apart cathode, and at least one electron-transporting layer disposed between the spaced-apart anode and cathode. Such EL devices provide lower drive voltage, improved power efficiency, and longer operational lifetime.
