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.
