The synthesis of luminescent metal complexes is a very challenging task since they can be regarded as the
starting point for many different areas. Luminescent complexes, in fact, can be used for technological,
industrial, medical and biological applications. They consist of two main parts: the central core of the
complex, a metal atom, and various organic ligands bonded to it.
Among all the transition metal complexes, Iridium(III) ones show the best photophysical properties:
generally, they have high quantum yields, very long lifetimes and possess easily tunable emissions
throughout the visible range.
During my PhD I prepared different families of Ir(III) complexes suitable for various applications.
In detail, my thesis deals with the synthesis of new functionalized chelating ligands that have been used to
obtain phosphorescent Ir(III) complexes. In particular I synthesised isocyanides, phenyltetrazole and pyridiltriazolylidene
derivatives and various corresponding Ir(III) complexes with peculiar photophysical properties,
suitable for the preparation of electroluminescent devices.
Moreover, I synthesized pyridiltriazole chelating ligands for the preparation of Ir(III) complexes able to be
embebbed in nanoparticles. At the same time, I set up the synthesis of various carbazole-terpyridines systems
containing substituent of different length and aromatic character.
During my studies, I enhanced my knowledges about the techniques for the spectroscopical characterization
of the obtained compounds, such as mono- and bidimensional and VT- NMR, UV-vis and spectrofluorimetry.
