Abstract | A simple and straightforward synthesis of a tetranuclear copper(I)-pyridine-iodide cluster is described as a laboratory experiment for advanced inorganic chemistry undergraduate students. The product is used to demonstrate the fascinating and visually impressive phenomenon of luminescence thermochromism: exposed to long-wave UV light, the crystalline solid shows a bright yellow fluorescence at room temperature and an equally intense blue-violet fluorescence when cooled in liquid nitrogen. The procedure was also extended to several other pyridine ligands to allow students to synthesize different clusters and compare their photophysical behavior. (Contains 1 table, 1 scheme, and 6 figures.) (As Provided). |
