技术领域
本发明涉及有机电致发光技术领域,特别涉及一种激基复合物及其应用、以及包含该激基复合物的有机电致发光器件。
背景技术
有机电致发光器件(Organic Light Emission Diodes,OLED)是一类具有类三明治结构的器件,包括正负电极膜层及夹在电极膜层之间的有机功能材料层。对OLED器件的电极施加电压,正电荷从正极注入,负电荷从负极注入,在电场作用下正负电荷在有机层中迁移相遇复合发光。由于OLED器件具有高亮度、快响应、宽视角、工艺简单、可柔性化等优点,该技术已被广泛应用于照明灯具、智能手机及平板电脑等产品的显示面板,是一种发展快、技术要求高的新显示技术。
效率好、寿命长的OLED器件通常需要器件结构以及各种有机材料的优化搭配。常见的功能化有机材料有:空穴注入材料、空穴传输材料、空穴阻挡材料、电子注入材料、电子传输材料,电子阻挡材料以及发光主体材料和发光客体(染料)等。为了制备驱动电压更低、发光效率更好、器件使用寿命更长的OLED,材料界一直致力于开发新的有机电致发光材料以实现器件低启动电压、高发光效率和更优的使用寿命。
激基复合物(exciplex)材料单线态-三线态能隙(ΔEST)非常小(<0.2eV),三线态激子可以通过反向系间窜越(RISC)转变成单线态激子发光,器件的内量子效率可以达到100%。除此之外,激基复合物还可以降低器件的驱动电压,引起了科研界和产业界的广泛关注。但是,蓝光激基复合物难于实现且激基复合物发光特性难于调控。现有技术中有通过在电子给体型材料或电子受体型材料上引入惰性位阻基团如叔丁基、环烷基等来增大二者之间的距离,对激基复合物光色及RISC进行调控,但是这会造成激基复合物传输能力降低而使器件驱动电压升高,大大限制了激基复合物材料在低电压、高效率和长寿命有机电致发光器件中的进一步应用。
