Abstract:

To develop the ability of undergraduates to analyze and solve problems using the knowledge they have acquired, this study designs a comprehensive experiment to study the structure-property-effect relationship of newly reported copper phenylacetylene (Ph-C≡C-Cu)-based functional materials. This experiment was designed based on the latest research results by thoroughly examining the basic chemistry knowledge of undergraduate students. In this experiment, different functional group modified Ph-C≡C-Cu materials were prepared, and their structures and physicochemical properties were characterized. Subsequently, their adsorption and photocatalytic degradation activities of methyl orange (MO) were studied. As a basic teaching experiment for undergraduates, this comprehensive experiment examined students' understanding, mastery, and application of the electronic effects of different functional groups in organic chemistry, liquid-solid interface interactions, solid adsorption in solution, catalytic reaction kinetics, and the determination of reaction orders in physical chemistry. Further summarizing and discussing the structure-property-effect relationship of new Ph-C≡C-Cu-based functional materials can encourage and guide undergraduates to design the structures of the target functional materials with specific properties and practical applications based on their knowledge and theories they have mastered, which will cultivate their reverse thinking mode and improve their ability to combine theory and practice.
