摘　　要：作为席夫碱家族结构最小的成员,亚水杨基甲胺能否用作分子开关,在实验和理论上没有统一的答案。针对此问题将最新的科研成果转换为实验教学内容,设计了立足教学面向科研的亚水杨基甲胺分子激发态动力学行为的研究型实验。实验内容包括文献调研、模型构建、电子结构计算、非绝热动力学模拟及数据处理与分析6部分。实践表明,该设计性实验不仅提高了学生的实验方案设计能力、计算结果分析能力,还培养了学生的科学怀疑精神与团队合作精神,学生科研论文的写作与大学生科学创新项目申请打下良好基础。The Schiff family is widely used as the molecular switches,and the salicylidene methylamine is one of the simplest aromatic Schiff bases.However,whether the salicylidene methylamine system can be used as molecular switches is still at debate because of the disagreement between the experimental and theoretical results.By transforming the current scientific research frontier into experimental teaching practice,an experiment of“the photodynamical behavior of the salicylidene methylamine”is designed.Six parts such as beforehand literature research,model construction,electronic structure calculation and dynamic simulation,and later data processing and analysis are included in this experimental process.The teaching practice shows that this design not only improves the students’experimental scheme design ability and the data analysis ability,but also cultivates the scientific skepticism.Outstanding achievements are obtained in the scientific publications and applications of creative plans.
