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.
Azatriphenylene衍
生物及其在电致发光装置中的使用,该装置包括阳极,间隔的阴极,以及至少一个位于间隔的阳极和阴极之间的电子传输层。这样的EL设备提供更低的驱动电压、改善的功率效率和更长的操作寿命。
