本实验基于Suzuki偶联反应，以4-三苯胺硼酸和5-溴-2-羧基噻吩为原料，经加热、回流、过滤、萃取、干燥等单元操作，合成了5-(4-(二苯胺)苯基)噻吩-2-羧酸钾(TTC)，并利用核磁氢谱、紫外-可见吸收光谱、荧光发射光谱对该物质的结构及光物理性质进行了系统的研究。实验结果表明，所合成分子表现出高效的蓝光发射及显著的聚集诱导发光(AIE)性质。基于此，本实验以荧光功能分子的实际应用为导向，设计了潜指纹检测成像的实验环节。该有机荧光分子可作为指纹显影剂，快速高效地实现高质量指纹图像显影和三级指纹特征检测，并通过MATLAB指纹识别系统对提取的指纹进行对比。该实验实现了化学合成-材料表征-应用探索的教学闭环。经推广，该实验现象明显，重复性好，展示度高，有利于激发学生学习兴趣。通过实验训练，学生不仅掌握交叉学科知识，更建立起“分子设计-性能调控-功能应用”的系统研究思维，为培养创新性人才提供了优质的实践平台。
