Description

一种有机电致发光化合物及其应用
技术领域
本发明涉及有机发光材料技术领域,更具体的说是涉及一种有机电致发光化合物及其应用。
背景技术
有机电致发光元件是利用了如下原理的自发光元件:通过施加电场,利用由阳极注入的空穴与由阴极注入的电子的复合能使荧光性物质发光。它具有如下结构:阳极、阴极以及介于两者之间的有机材料层,为了提高有机电致发光元件的效率和稳定性,有机材料层通常包括具有不同材料的多层,例如空穴注入层(HIL)、空穴传输层(HTL)、发光层、电子传输层(ETL)和电子注入层(EIL);在这种有机发光元件中,当在阳极和阴极之间施加电压时,来自阳极的空穴和来自阴极的电子注入有机材料层,产生的激子在迁移至基态时产生具有特定波长的光,其中空穴传输层可改变空穴到发光层的空穴传输效率、发光效率、寿命等。
