摘要:

为提高化学及相关专业本科生对超分子化学及耗散结构的认知并锻炼其大学化学综合实验技能,设计了基于鸟苷5’-单磷酸二钠盐与尿素-脲酶计时反应的超分子组装体动态重构综合实验。本实验主要包括基于计时反应的非平衡超分子组装体系构建方法、结构表征、组装体动态重构机制探究等内容。通过科教融合的形式提高学生对科学研究的兴趣,培养学生科学思维;通过本实验的实践,可提升学生综合技能。

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.
