Preparation and Luminescence Thermochromism of Tetranuclear Copper(I)-Pyridine-Iodide Clusters
Parmeggiani, Fabio; Sacchetti, Alessandro
Journal of Chemical Education, v89 n7 p946-949 Jul 2012
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.)
