Giuseppe D’Alfonso

DALFONSO

Full Professor of Inorganic Chemistry at DC UNIMI

Expertise: inorganic synthesis and spectroscopical characterization

Born in 1947, he received the Laurea degree cum laude in Chemistry from the University of Milan in 1970. After a scholarship in the Chemical Physics department, he spent four years in a research centre of Montedison (Bollate, Mi), performing kinetic studies devoted to the optimization of the production of intermediates for polymers productions. In 1980 he joined the Department of Inorganic, Metallorganic and Analytical Chemistry of University of Milan, where he is still full time researcher in the field of inorganic chemistry. In 2000 he was appointed Full Professor of General and Inorganic Chemistry at the same University.

From 2008 to 2010 he was a member of the Advisory Board of Organometallics (ACS journal).

He represents the Università degli Studi of Milan in the board of directors of the Italian Interuniversity Consortium on Material Science and Technology (INSTM).

He has published 150 papers on peer reviewed international journals, with an h-index ≥ 22.

His main expertise is in the synthesis of coordination compounds, but his research interests are many and different. His activity initially focused on the chemistry of hydrido or carbido carbonyl clusters, and then progressively moved towards the chemistry of the metal-hydrogen bond, the reactivity with organic fragments, and the characterization by NMR spectroscopy of unstable reaction intermediates, weak interactions, dynamic processes and association equilibria. Further research themes concerned the reactivity of complexes on silica surface or with silanolate/silsesquioxane groups and the reactivity and dynamics of fluoroarylboranes, in the context of a contract of Scientific and Technological Research with Basell Poliolefine SpA, for the study of co-catalysts for olefin polymerization. More recently this expertise has been applied to the synthesis of inorganic nanoparticles and of luminescent metal complexes, which have been successfully used for the preparation of very efficient electroluminescent devices, as well as for cell imaging. His current research concerns the development of novel molecules and materials for optoelectronic devices and for biomedical theranostic applications. He was responsible of one of the research units of the Milan University in a large national four-year project (FIRB 2003-RBNE033KMA, “Molecular compounds and hybrid nanostructured materials for photonic devices”, led by Prof. R. Ugo) and has also been leader of the Milan Research Unit in four “Scientific Project of Primary National Interest” (PRIN), the latter one (2009PRAM8L) concerning the preparation of novel complexes for solar cells.
