Résumé

Square planar platinum(II) complexes are rather well known compounds in chemotherapeutic cancer treatments. But they show also very interesting electro- and photoluminescence properties. Research in organic light emitting diodes (OLED) being trendy, the interest of the scientists for such complexes has grown in these recent years. [1] Recently Mauro, De Cola and co-workers reported a new family of square planar Pt(II) complexes [2-4] containing a tridentate N-donor ligand, the 2,6-bis(3-(trifluoromethyl)-1H1,2,4-triazol-5-yl)pyridine (pyC5-CF3-tzH2). The coordination sphere is completed by various monodentate ligands. These coordination compounds showed remarkable supramolecular assembling properties and high photoluminescence quantum yields due to non-covalent intermolecular (metalmetal and π–π) interactions.
