摘要
电子转移是自然界中普遍存在的现象,伴随着电子转移过程的发生,材料的物理和化学性质也由于电子组态的不同而产生变化。外界刺激诱导的电子转移配合物在智能响应材料和分子传感领域具有潜在的应用价值。本文在科研成果的基础上设计了一个综合实验——具有可逆热致电子转移效应的智能分子材料制备及性能研究。实验过程包括:金属有机配合物合成、薄膜材料制备、仪器分析表征、材料热致变色效应研究等,涵盖无机化学、分析化学、物理化学等多门化学课程主要相关知识点,具有很好的综合性和学科前沿性。通过此实验,学生可以深入理解相关化学理论基础知识,掌握金属有机配合物的合成与表征,了解热传感器件的响应机理,激发学生的科研兴趣,提高学生的综合科研素质。
The charge transfer is a ubiquitous phenomenon in nature,and the physicochemical properties of the materials change due to the change of electronic configurations during the charge-transfer process.Charge transfer complexes with tunable properties actuated by external stimuli have potential applications in the fields of smart responsive materials and molecular sensing.In this paper,a novel comprehensive experiment is designed based on scientific research achievements:the preparation and properties of smart molecular materials with reversible thermal-induced charge-transfer effect.The experiment includes synthesis of metal-organic complexes,preparation of thin-film materials,instrumental analysis of the materials and research on thermochromic effect of materials,in which the main relevant knowledge points of most chemistry courses could be covered.The experiment is comprehensive and presents frontiers of disciplines.Through this experiment,students can not only consolidate the basic knowledge of relevant chemical theory including mastering the synthesis and characterization of metal-organic complexes and understanding the response mechanism of thermal sensor devices,but also can be attracted by the scientific research,and their scientific literacy can be improved.
