Received Date: 13 October 2023
Revised Date: 8 January 2024

In this paper, the experimental design of undergraduate teaching was conducted based on the hot research fields of molecular switches and aggregation-induced luminescence. Photochromic diarylethene was skillfully integrated into a tetraarylethene system with aggregation-induced luminescence performance, and a new type of photoswitchable fluorescent molecular switch with both color-changing and luminescence functions was prepared. By integrating science and education, the scientific research frontier was introduced into undergraduate experimental teaching. A comprehensive experimental exploration was carried out from the aspects of material preparation, separation and purification, structure characterization and performance test. The molecular design of this experiment is concise and novel, the content is rich, and the phenomenon is obvious. On the basis of comprehensively applying and consolidating the basic theories and basic operations of undergraduate learning, this work can stimulate students’ interest in scientific research and cultivate the scientific spirit of unity and cooperation, breakthrough and innovation.
