Abstract:

In the study, we introduced a new organic fluorescence molecule into organic laboratory teaching. A novel course content about fluorescent dimethylaminosylstyrylbenzoxazole was designed. The clear proton response properties of the product can be observed directly. The experiment has many advantages, including new reaction mechanisms, low laboratory risk, simple in operation, observable process changes, and good environmental friendliness. Furthermore, this laboratory course can be divided into a series of unites, which is suitable for different lab teaching time requirements. According to the experiment. We have received good teaching effects. This experiment not only cultivates student's basic operation and comprehensive ability, but also stimulates students' research interest.
