Abstract:

The design of this experiment includes the synthesis of Fe(Ⅱ) spin crossover compounds and the study of thermochromic properties. The effects of temperature and solvent on the spin state of the complex are explored. Thermochromic composite polymers with certain processability are prepared and characterized by various methods. From the verification of basic principles to the design of modified practical materials, the experiment involves multiple disciplines such as inorganic chemistry, analytical chemistry, polymer science and materials science. Through the entire synthesis process, characterization, property regulation, and application, students' knowledge, skills, and accomplishments are fully trained.

Key words: Thermochromism, Spin crossover, Coordination field, Hydrogen bond, Polymer film
