Abstract:

Organic functional materials have attracted significant research attention in organic chemistry. Introducing the synthesis and characterization of advanced organic functional materials into basic organic chemistry experiments can enrich the study content and promote the connection between teaching and academic achievements. Therefore, in this project, one of the research frontiers, i.e., organic long-afterglow materials, were selected and combined with the laboratory teaching of nucleophilic aromatic substitution. This project can help students understand the key role of synthetic reactions in constructing organic functional materials. Furthermore, extending the knowledge system to modern spectroscopy technologies can help students understand correct scientific concepts. This experiment completes the systematic teaching of the "synthesis-molecular structure-photoelectric properties" knowledge chain, thereby developing students' science literacy and continual innovatory capacity.

Key words: Organic long-afterglow materials, Nucleophilic aromatic substitution, Fluorescence spectroscopy, Science and education integration
