构造深蓝的新途径导致聚集的排放(AIE ) 材料被探索了,它由二不同策略控制变化形式,为器官的轻射出的二极管的商品化做大步。以便弄短 intramolecular 变化形式长度, triphenylethylene (tPE ) 被利用到构造蓝色 AIEgens 同样外部的组而不是 tetraphenylethylene (TPE ) ,著名 AIE 星分子,产出 3,4-BtPE-PI, 4,4-BtPE-PI 和 4,4-BtPE-PPI 的三蓝 AIEgens。Nondoped electroluminescence 设备被把这三 AIEgens 用作射出的材料层制作, 3.8 的最好的表演 ? 最大的当前的效率在委员会国际歌 de lEclairage 完成了的 cd/A 协调(0.17, 0.18 ) 。
The new approaches to construct deep blue aggregation-induced emission (ALE) materials have been explored, which control the conjugation by two different strategies, to make a great step for the commercialization of organic light-emitting diodes. In order to shorten the intramolecular conjugation length, triphenylethylene (tPE) was utilized to construct blue AIEgens as peripheral groups, instead of tetraphenylethylene (TPE), the famous AIE star molecule, to yield three blue AIEgens of 3,4-BtPE-PI, 4,4- BtPE-PI and 4,4-BtPE-PPI. Nondoped electroluminescence devices are fabricated by using these three AIEgens as the emitting material layer, the best performance of 3.8 cd/A as the maximum current efficiency achieved at the commission internationale de l'Eclairage coordinates of (0.17, 0.18).
