摘　　要：现有实验教学中使用的醛胺缩合反应普遍存在反应时间长、反应程度低及制备过程略微复杂等问题,阻碍了该类实验在本科教学中的开展,影响了相关知识点的生动呈现。同时,现有实验主要围绕亚胺的合成过程进行教学,较少探究物质的功能特性,导致其实验设计在性能测试及应用呈现上存在一定的限制。针对上述问题,通过选择合适的反应底物,介绍了2种简单绿色的席夫碱实验合成方法,有效优化了相关实验内容,简化了实验过程,利于结合醛胺缩合等相关知识点进行本科教学实验的开发设计。此外,也结合“聚集诱导发光”这一国人引领的前沿研究领域,以席夫碱的合成反应为切入点,促进学生更好地了解国际学术发展前沿,激发学生学习兴趣,开拓学生科研视野。同时,根据不同层次的教学需求,本实验还可进一步引入核磁共振波谱、高分辨质谱、紫外吸收光谱以及荧光发射光谱等多种表征方法,为全面提高学生的综合实验素养提供支撑。It is noted that the problems of long time,low yield and complicated preparation process for aldehyde-amine reactions still seriously limit their application in the experimental teaching.Also,most of these reported reactions are mainly focused on their preparation and synthesis,their functionality is seldomly investigated,thus limiting the teaching in material properties and applications.Based on these considerations,two simple but green synthetic methods to prepare Schiff base is introduced here in this paper by selecting the suitable substrates.This well optimizes the experimental content and simplifies the experimental process,thus facilitating the undergraduate experimental teaching.Notably,the concept of aggregation-induced emission is also introduced here,which helps the students to know more about the corresponding research topics,then stimulating their interest in learning.Moreover,depends on the demands of teaching,several experimental techniques and characterization methods,such as NMR Spectrometer,UVVis Spectrometer and Fluorescence Spectrometer,can also be introduced,to further cultivate students'comprehensive ability.
