Design, synthesis, characterization and application. This four-steps sequence drives us in pursuing our scientific activity that deals with the making of new luminescent metal complexes that can find their application in material science, bioinorganic chemistry, photocatalysis and in the conversion of solar energy.

Within the framework of the research focussed on coordination chemistry, we have dedicated significant attention to the synthesis and characterization of luminescent metal complexes. In particular, this activity has been pursued by preparing and studying the electrochemical and photophysical properties of the metal tetrazolate derivatives that belong to some of the most popular classes of luminescent metal complexes, such as Ru(II) polypiridyls, tris carbonyl Re(I)diimines, Ir(III) and Pt(II) cyclometalates and Cu(I)-based complexes.

In many cases, the results that were obtained from such fundamental studies have addressed the application of our complexes in the field of materials science, as witnessed by the fabrication of high-efficiency OLED-type devices containing Ir(III) or Pt(II)-tetrazolate based species as the emitting layer. As the result of long term and fruitful scientific collaborations(Dr. M Massi of Curtin University, Perth), we have extended our research to different kind of ligands (i.e. triazoles, NHC ligands, etc) and to different types of “hybrid materials”, such as those represented by calixarene-based polymers doped with various lanthanide ions.

In addition, we are focussing on the study of a numebre of new Re(I)-tetrazolate complexes as luminescent probes for biologically active molecules.
