A high triplet energy, high thermal stability oxadiazole derivative as the electron transporter for highly efficient red, green and blue phosphorescent OLEDs
A high glass transition temperature (Tg = 220 °C), high triplet energy gap (ET = 2.76 eV) and high electron mobility material bis(m-terphenyl)oxadiazole was readily synthesized. It can serve as a universal electron transporter for blue, green and red phosphorescentOLEDs with excellent efficiencies. The material shows high current density compared to other electron transport materials and exhibits
高玻璃化转变温度(Ť克= 220℃),高三重态能隙(Ë Ť = 2.76电子伏特)和高电子迁移率的材料的双(米-三联苯)二唑被容易地合成。它可以用作具有出色效率的蓝色,绿色和红色磷光OLED的通用电子传输器。与其他电子传输材料相比,该材料显示出高电流密度,并且由于主体从2,5-di([1,1':3 ',1''-三联苯基] -5'-基)-1,3,4-恶二唑(TPOTP)连接到主体材料上。对于绿色PhOLED,最大外部量子效率(EQE)超过25%,电流效率为97.6 cd A-1和100.6 lm W -1的功率效率得以实现。使用TPOTP作为电子传输体的红色和蓝色设备也显示出EQE高于23%,并且实际亮度水平上的滚降效率非常低。

The synthesis of C3-symmetrical tristriazolotriazines with conjugated arms and lateral alkoxy side chains was performed by a threefold condensation of cyanuric chloride with tetrazoles. Conjugated π segments include phenyl, tolane, and its phenylethynyl-elongated homologue. Disclike and a dendritic molecule have been obtained, and two compounds with a 3,4,5-tris(octyloxy) substitution form broad thermotropic
