一种新型有机质子响应荧光分子的合成在实验教学中的设计与探索

Design and Exploration of a Novel Organic Proton Response Fluorescence Molecule in Laboratory Teaching

本实验将最新的科研热点——有机发光材料引入实验教学,开发了基于一个荧光分子二甲氨基苯乙烯基苯并噁唑的合成实验,并考查了其质子响应性质。本实验反应温和易控,操作简单,现象明显,绿色环保,并且可以用于模块化教学,拆分成多个环节实验,适合不同学时的实验教学要求,既可培养学生的基本操作,又能激发学生的实验兴趣,锻炼学生的综合能力。

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.
