N-Heterocyclic Carbene Coinage Metal Complexes Incorporating Pyrene Chromophore: Synthesis, Structural Motifs, and Luminescent Properties

Résumé

N-heterocyclic carbenes (NHCs) are strongly coordinating ligands and have proven themselves as the ligands of choice in a wide-range of the chemistry spectrum spanning from organometallics, catalysis to medicinal chemistry as well.1-2 More recently they have been used with success to design stable luminescent organometallic and coordination complexe.3-4 This is because they tend to push the 3dd dark states high in energy and thus avoiding the deactivation processes of the low-lying MC (metal-centered) transition states. In this Poster we describe the design of novel class of luminescent NHC-coinage metal complexes containing a pyrene chromophore (Figure 1). All complexes were fully characterized and their molecular structures were ascertained by X-ray diffraction studies. The nature of the coinage metal center and the alky substituents on the carbene unit were probed to tune their electronic properties generating blue emitters at room temperature.
