their high thermal stability, electrochemical reversibility, and wide band gap useful for organic light-emitting diodes (OLEDs), especially blue OLEDs. Oxidation of cyclotriveratrylene (CTV) to the corresponding diketone and subsequent bromination resulted in an unexpected rearrangement to a highly functionalized 9-aryl-10-bromoanthracene derivative, which was employed in Suzuki couplings to synthesize
电致发光的9,10-二芳基蒽因具有高的热稳定性,电化学可逆性和可用于有机发光二极管(OLED),尤其是蓝色OLED的宽带隙,已被证明是有机电致发光中有希望的主体和空穴传输材料。 。环三碳四烯(CTV)氧化为相应的二酮并随后溴化,导致意想不到的重排为高度官能化的9-芳基-10-溴蒽衍生物,该衍生物在Suzuki偶联反应中用于合成一系列9,10-二芳基化合物用于制备OLED的蒽衍生物的结构类似物,但功能化程度更高,除了被羧酸部分取代外,还包括供电子甲氧基。
