Recently, the comprehensive innovation experiments for undergraduates played important roles in enriching the teaching contents, establishing new teaching models, and enhancing students’ innovative ability. However, due to the limited time for undergraduates, and their lack of understanding of the background and content of innovation experiments, how to propose a proper comprehensive innovation experiment is very important, and it is also one of the key steps to realize the teaching and training goals. Based on these considerations, the research on “aggregation-induced emission” (AIE) is proposed as a comprehensive innovation experiment. By comparing the photo-physical properties of AIE active tetraphenylethylene and traditional fluorescent material of 4’,5’-dibromofluorescein, and investigating its potential application in fingerprint imaging, it is anticipated that the content in innovative laboratory teaching can be well enriched. While expanding students’ understanding of the relevant background knowledge, their practical ability in fluorescence spectrometers and some other instruments can also be improved. The implementation of this comprehensive innovation experiment can then cultivate and improve students’ ability to discover and solve problems, and finally provide new exploration ideas for their scientific training and innovative thinking.
