A diphenyl quinoline (DPQ)-conjugated derivative and bromine-activated DPQ (Br-DPQ) were synthesized in an inert gas atmosphere at 140 °C using Friedlander condensation. The compounds showed blue emission under a UV source. The structures were characterized by X-ray diffraction and Fourier transform infrared spectroscopy. The photoluminescence properties of the compounds were analysed using excitation and emission spectra. The synthesized organic phosphors shows bright emission in the blue region, with peaks at 445 and 453 nm, respectively, for DPQ and Br-DPQ in the powder form. The physical and photoluminescence properties of these organic compounds reveal promising blue emitters for high-efficiency organic light-emitting diodes.
在140°C的惰性气体氛围中，使用弗里德兰德缩合反应合成了一种二苯基喹啉（DPQ）共轭衍生物和溴活化的DPQ（Br-DPQ）。这些化合物在紫外光源下呈现蓝色发射。通过X射线衍射和傅里叶变换红外光谱对其结构进行了表征。利用激发光谱和发射光谱分析了这些化合物的光致发光特性。合成的有机磷光体在蓝色区域呈现明亮发射，粉末形式的DPQ和Br-DPQ的发射峰分别位于445和453nm处。这些有机化合物的物理和光致发光特性表明它们有望成为高效有机发光二极管的蓝色发射体。
