Abstract: 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.

Key words: Copper (I) complexes, Copper content analysis, Luminescent performance, Comprehensive chemical experiment
