at the same time, blue-shifted of fluorescence emission wavelength was observed when the C-5 position of 8-hydroxyquinoline was substituted by electron-withdrawing group. When the C-4 position of 8-hydroxyquinolie was substituted by methyl or the C-5 position was substituted by sulfonic acid group, the corresponding zinc complexes had higher fluorescence intensity than 8-hydroxyquinolie zinc.
由8-羟基喹啉金属络合物生产的有机发光二极管(OLED)在现代电致发光器件中起着至关重要的作用。本文采用不同的方法合成了一系列的8-羟基喹啉衍生物,并制备了相应的锌金属配合物。测量了配合物的紫外和荧光性质,旨在了解喹啉环上的取代基对配合物的荧光性质的影响。当8-羟基喹啉的C-5被卤素取代时,荧光发射波长发生了红移,同时,当8-羟基喹啉的C-5位置为2时,观察到荧光发射波长发生了蓝移。被吸电子基团取代。
