series of 9-(fluoren-2-yl)anthracene derivatives bearing either thiophene (FATh), triphenylamine (FAT and FATT) or pyrene (FATP) moieties as substituents have been designed, synthesized, and characterized as non-doped blue emitters for organic light-emitting diodes (OLEDs). Their optical, electrochemical and thermal properties have been investigated, and their molecular structure-property relationships
一系列带有噻吩 (FAT)、三苯胺 (FAT 和 FATT) 或芘 (FATP) 部分作为取代基的 9-(芴-2-基)蒽衍生物已被设计、合成并表征为无掺杂的蓝色发射体有机发光二极管 (OLED)。研究了它们的光学、电化学和热性能,并评估了它们的分子结构-性能关系。所有 FAT、FATT 和 FATP 化合物都具有结合蓝光发射和空穴传输的特性,并在溶液中显示出稳定的无定形态,具有高荧光量子产率(高达 89%)和在 OLED 器件中的强亮度,而 FATh 则表现不佳光致发光和电致发光特性。制造并表征了高效、无掺杂的蓝色和基于 Alq3 的绿色 OLED。分别实现了具有最大亮度效率和 CIE 坐标为 3.17 cd A-1 和 (0.13, 0.14) 以及 3.81 cd A-1 和 (0.28, 0.50) 的蓝色和绿色器件,其中 FATT 具有 4-bis[ 4'-(二苯基氨基)联苯基-
