Abstract:

To improve the undergraduate understanding of supramolecular chemistry and dissipative structures and train their ability to conduct comprehensive chemical experiments, this paper proposes an experiment of dynamic reconfiguration of supramolecular assemblies that is based on guanosine 5'-monophosphate disodium salt and the urea-urease clock reaction. This experiment covers the construction approach and structural characterization of the nonequilibrium supramolecular assembly system based on the clock reaction, as well as the exploration of the mechanism of the dynamic reconfiguration of the assemblies. Integrating science and education can prompt students' interest in scientific investigation, cultivate their scientific thinking, and improve their comprehensive skills.

Key words: Clock reaction, Nonequilibrium processes, Supramolecular assembly, Urease, Comprehensive chemical experiment
