四苯乙烯及其衍生物被广泛报道具有典型的聚集诱导发光（AIE）性能，在有机发光二极管、荧光离子探针、生物化学成像等诸多领域有着广阔的应用前景。以此为背景，可以将相关前沿议题转化为本科综合实验教学方案。本文针对现有的实验教学方案设计进行了探究和改进，在原有使用McMurry偶联反应制备四苯乙烯的实验方案基础上，利用生色团上不同取代基的推拉电子效应设计平行对照试验，合成溴代、甲氧基取代的四苯乙烯衍生物，实现了荧光发射光谱最大峰波长的显著移动，使得在紫外灯下即可观察到荧光从蓝色到黄绿色的变化。利用超声辅助合成的方法，成功将反应时间从原有的6-8 h压缩至2 h，使之更适应本科教学实验所需的时间空间。除光学性能表征外，本实验还综合了循环伏安法表征产物的能带结构。本实验针对原有方案进行了诸多改进，引入平行实验锻炼科学思维、别出心裁地引入超声辅助合成法，极大地缩短了反应时间，展现出较强的前沿性、绿色性和高效性。
