摘　　要：介绍了一个研究型综合化学实验——具有异构发光变色的双核铜(I)配合物的合成、铜含量分析和发光性能研究。本实验基于氧化还原反应和配位反应合成Cu(I)配合物,采用薄层色谱法判断合成反应进程,运用配位滴定法测定其铜含量,利用荧光光度法和荧光定量分析法测定固态荧光以及判断产品的纯度。本实验综合了无机化学、有机化学、分析化学的基础知识和实验技能以及大型仪器的学习和操作,同时体现了发光金属配合物这一科研热点,探究物质结构与性质的关系。通过本实验的实践,学生在巩固所学实验知识和实验技能的同时,训练了运用所学知识解决实际问题的综合能力,有利于学生初步建立科学的思维方式和研究能力。This paper presents a research-oriented comprehensive chemical experiment on the synthesis,copper content analysis,and luminescence performance study of binuclear copper(I)complexes with isomeric luminescence shift.In this experiment,Cu(I)complexes were synthesized through redox and coordination reactions.Thin-layer chromatography was used to determine the reaction endpoint.The copper content in the complexes was then measured by coordination titration method.Finally,the fluorescence spectroscopy and fluorescence quantitative analysis were employed to evaluate the solid-state fluorescence and the purity of the product.This experiment integrates foundational knowledge and experimental skills from inorganic chemistry,organic chemistry and analytical chemistry,as well as the learning and operation of sophisticated instruments.It also reflects the current research hotspot of luminescent metal complexes and explores the relationship between material structure and properties.By participating in this experiment,students not only reinforce their learned experimental knowledge and skills,but also develop their comprehensive ability to apply the knowledge to solve practical problems,fostering an initial scientific mindset and research ability.
