Abstract Through an in-depth introduction to the concepts of esterification reaction, transesterification reaction and aggregation-induced emission, as well as a comparative analysis of different synthesis methods of hyperbranched polycarbonate, students are guided to understand the cultural ideas that “tradition breeds innovation”. Using diethyl carbonate and glycerol as raw materials, a simple transesterification polycondensation reaction was used to design and synthesize hyperbranched polycarbonate with aggregation-induced emission effect. The ultraviolet absorption and fluorescence properties of hyperbranched polycarbonate were studied by UV-Vis spectrophotometer and fluorescence spectrometer. Finally, the aggregation morphology and size of hyperbranched polycarbonate were studied by scanning electron microscope and laser particle size analyzer to explore the luminescence mechanism. The whole experiment teaching starts from perspective of science, and allows students to understand the cultural connotation of “tradition breeds innovation” from the teaching theory of synthesis principle and luminescence mechanism, which not only cultivates students’ enthusiasm and interest in scientific research, but also allows students to master the operation of advanced equipment operating skills, cultivate students’ comprehensive experimental ability and humanistic qualities.
