  • The synthesis of luminescent metal complexes is a very challenging task since they can be regarded as the starting point for a lot of different areas. Luminescent complexes, in fact, can be used for technological, industrial, medical and biological applications. During my PhD I worked with different metals having distinguishing intrinsic properties that make them different from each other and, in particular, more or less suitable for the different possible uses. Iridium complexes show the best photophysical properties: they have high quantum yields, very long lifetimes and possess easily tunable emissions throughout the visible range. On the other hand, Iridium is very expensive and scarcely available. The aim of my work concerning this metal was, therefore, to synthesize ligands able not only to form luminescent complexes, but also able to add functionalities to the final complex, increasing its properties, and therefore its possible practical uses. Since Re(I) derivatives have been reported to be suitable as probes in biological system, and the use of Re(I) reduces the costs, the synthesized bifunctional ligands containing a pyridine-triazole and a biotin unit were employed to obtain new Re(I) luminescent probes. Part of my work involved the design and synthesis of new ligands able to form stable complexes with Eu(III) and Ce(III) salts, in order to obtain an emission in the range of visible light: these two metals are quite cheap and relatively non-toxic compared to other heavy metals. Finally, I plan to synthesize organic derivatives that already possessed an emission thanks to the presence of other many chromophoric groups and can be able to link the Zinc (II), a low cost and especially non-toxic “green” metal. Zinc has not its own emission, but when it sticks to ligands, it increases their photophysical properties.
