摘要
设计和合成了7个新型苯并噻唑基-吡唑啉类化合物,通过元素分析和红外光谱检测,确定了化合物的结构,荧光检测结果表明它们的荧光强度为36.1～69.2,荧光强度的大小与衍生物中的取代基有关,溴和甲氧基取代衍生物具有较高的荧光性。
Seven new benzothiazolyl pyrazoline compounds were synthesized and their structures determined by IR and fluorescent spectra. The results showed that fluorescence intensity was related to the substituents of the compounds; the compounds substituted with Br or methoxy group gave stronger fluorescence.
