【摘要】：本研究針對藍光主體材料相對缺乏的現(xiàn)狀,利用有機電致磷光器件高效率的優(yōu)勢,選擇1,2,4-三唑為電子傳輸功能基團、咔唑為空穴傳輸功能基團,設計、制備了新型主體材料oCzTz。通過鄰位取代方式實現(xiàn)了分子立體構型高度扭曲,從而使分子的三重態(tài)能量達到3.01eV;oCzTz具有較高的熱分解溫度(353℃)和玻璃化轉(zhuǎn)變溫度(110℃);量化計算顯示,分子的前線軌道在咔唑和三唑基團之間高度分離。以oCzTz為主體、以FIrpic為發(fā)光客體的天藍光電致磷光器件啟亮電壓為3.4V,電流效率和功率效率分別高達37.2cd·A-1和29.2lm·W-1,是以TPBI為電子傳輸層的同類器件的最高效率之一。
[Abstract]:Aiming at the relative lack of blue light main materials, a new type of main material, oCzTz. was designed and prepared by using the advantage of high efficiency of organic electroluminescent devices, which was selected as the electron transport functional group and carbazole as the hole transport functional group. The high distortion of the steric configuration of the molecule was realized by the method of ortho substitution, thus the triplet energy of the molecule reached 3.01 eVo CzTz with a higher thermal decomposition temperature of 353 鈩，
