利用聚集诱导发光现象观察分子定向运动的综合实验

Comprehensive Experiment on Visualizing Spontaneous Molecular Directed Motion with Aggregation-Induced Emission Property

设计了一个综合实验,将"聚集诱导发光(AIE)""分子机器"等科学前沿问题引入实验教学。该实验将化合物合成、荧光性能表征和化学动力学测试相结合,集有机化学、分析化学和物理化学相关内容于一体。通过课堂讲解和拓展阅读,使学生了解"分子机器"的基本概念,熟悉AIE现象产生的机理,提升学生利用理论知识解决实际问题的能力。本实验项目所需仪器简单、原料廉价、安全性高,适合于不同层次院校的本科实验教学。本实验项目基本学时为4学时,具有良好的可拓展性,建议在第五学期开设。更重要的是,本实验项目将课程思政与实验教学相结合,通过对AIE这一由中国人原创的科学理论的学习,增强学生的民族自豪感和自信心,激发学习热情。

A comprehensive experiment was designed in this work, which included the frontier science issues including "aggregation-induced emission(AIE)" and "molecular machine". The synthesis of compound, characterization of fluorescence property and test of chemical kinetics are combined in this experiment, which are related to organic chemistry, analytical chemistry and physical chemistry, respectively. Through class and network learning, students will learn about the basic conception of "molecular machine" and the mechanism of AIE phenomenon. Meanwhile, their abilities to solve practical problems with textbook knowledge will also be improved. The equipment using in this experiment is very simple, and the chemicalss are cheap and highly safety. Thus, this experiment is suitable for the experimental teaching of different universities and colleges. This experiment takes 4 class hours and is recommended to be set in the fifth semester. More importantly, since the AIE theory was an original scientific theory proposed by Chinese scientist, students’ national pride and learning passion will be enhanced memorably by the learning of AIE theory.
