Abstract:

While the existing university chemistry experimental teaching content is comprehensive, it often lacks a connection with cutting-edge scientific research, particularly in trending fields. In this study, we introduce the experiment "Kaempferol as an AIE-active natural product probe for selective Al³⁺ detection" into teaching practice. Through this experiment, students gain an understanding of the contributions made by Chinese scientists in the field of aggregation-induced emission (AIE) research. They also learn about the fundamental principles and applications of fluorescence, and gain intuitive insights into the distinctions between aggregation-induced emission and aggregation-induced quenching. The experiment encompasses complex structure analysis, spectral analysis, and instrumental characterization, offering both comprehensiveness and ease of operation. By engaging in this teaching practice, students develop their innovative thinking and comprehensive abilities, while simultaneously reinforcing their commitment to environmentally friendly development and enhancing a sense of national pride.
