摘要： 本文以流程图的形式直观展示了“具有异构发光变色的多核铜(I)配合物的制备及铜含量测定”实验从合成到分析的全过程，引导学生深入分析实验过程中的关键步骤及其对实验结果的影响，并对产物中铜含量测定过程所产生的“异常”现象进行了探讨和论证，对启发、培养学生“生疑、善疑、质疑、探疑”的意识和能力大有裨益。

关键词: 多核Cu(I)配合物, 异构发光变色, 制备及铜含量测定, 实验过程分析与探讨

Abstract: In the form of a flow chart, this paper directly shows the whole process of the experiment of “preparation of polynuclear copper (I) complexes with isomeric luminescence discoloration and determination of copper content”, guides the students to deeply analyze the key steps in the experiment process and their impact on the experimental results, discusses and demonstrates the “abnormal” phenomenon in the process of product analysis. It is of great benefit to enlighten and cultivate students' consciousness and ability of question.

Key words: Polynuclear Cu(I) complex, Isomeric luminescence discoloration, Preparation and determination of copper content, Experimental process analysis and discussion
