Effect of the substituents on the resulting luminescent properties

Abstract

There is a great interest in research on the study of gold(I) complexes with alkynyl and coumarin ligands. These compounds have a wide range of applications, like in medicine or as luminescent sensors. Alkynyl and coumarin ligands have been prepared in this project. Luminescent gold(I) compounds with phosphine and coumarin ligands have been synthesized. The obtained products have been characterized using techniques like 1H, 31P and 13C NMR, IR spectroscopies and mass spectrometry. The luminescent properties of these compounds have been studied by recording the absorption and emission spectra. The properties obtained have been compared to the ones from some gold(I) complexes that contain a similar coumarin ligand
