  摘要：

  以2-甲基-8-羟基喹啉和对位取代苯酚为主要原料合成了六种新颖的8-羟基喹啉衍生物，并通过1 H核磁共振（NMR），质谱（MS），紫外（UV）进行了表征光线分析和红外（IR）光线分析。还制备了它们与Eu（III）的配合物，并通过元素分析，摩尔电导率，UV光分析，IR光分析和热重-差热分析（​​TG-DTA）对其进行了表征。结果表明，该配体与Eu（III）离子配位良好，并具有优异的热稳定性。靶复合物的结构是EuY 1-6（NO 3）3 ·2H 2O.研究了目标配合物的发光性能，结果表明所有目标配合物均具有良好的发光性能，并且给电子基团的引入可增强相应配合物的发光强度，但添加电子退出组的效果相反。在所有目标络合物中，甲氧基取代的络合物（–OCH 3）的荧光强度最高，而硝基取代的络合物（–NO 2）的荧光强度最弱。结果表明，8-羟基喹啉衍生物对Eu（III）离子具有良好的能量转移效率。所有目标复
