摘要：

为了培养本科生综合运用所学知识分析和解决问题的能力，本文基于最新研究成果，深入挖掘其中所涉及的本科基础化学知识，设计了探究苯乙炔铜(Ph-C≡C-Cu)基新型功能材料结构-性质-效能关系的综合实验。本实验通过光热合成法制备了三种含不同官能团的Ph-C≡C-Cu基新型功能材料，利用红外(FT-IR)光谱、紫外-可见吸收(UV-Vis Abs)光谱和稳态水接触角表征了其结构和相关物理化学性质，并研究了其结构对于有机染料甲基橙(MO)的吸附和降解效能的影响。作为本科生基础教学实验，本实验考查了学生对有机化学中不同官能团的电子效应和物理化学中液-固界面相互作用、固体在溶液中的吸附、催化反应动力学以及反应级数的判定等知识的理解、掌握和应用。通过进一步总结与讨论Ph-C≡C-Cu基新型功能材料的结构-性质-效能关系，启发并引导学生以实际问题为导向，根据所学理论和知识，从源头上出发，对功能材料的结构进行设计，培养了本科生的逆向思维方式，提升了本科生理论与实践相结合的能力。

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.
