Jean-François Halet

Jean-François Halet received his B.Sc. (First Class Hons.) in Physical Chemistry from the University of Nancy, France (1981), his M.Sc. (Hons.) in Physical Chemistry from the University of Rennes, France (1982) in Physical Chemistry and his Ph.D. in Spectroscopy and Chemistry from the University Pierre-et-Marie Curie, Paris, France (1984) working with Professors G. Jaouen, IUF, and J.-Y. Saillard, IUF, on the electronic structure of organometallic clusters. Later, he received his D.Sc. in Chemical Sciences (1990) and his Research Habilitation (1991) from the University of Rennes, France. Following postdoctoral research with Professor D.M.P. Mingos, FRS, at the University of Oxford in England (1986-1987), he spent over a year as a Visiting Research Scientist with Professor R. Hoffmann (Nobel laureate 1981) at Cornell University, Ithaca, New York in USA (1987-1988). He was appointed as a Researcher Fellow at the CNRS University
of Rennes, France, in 1984, was promoted to 2nd class Research Director (Full Professor) in 1997 and to 1st class Research Director in 2008. From 2000 to 2003, he was the Head of the Laboratory of Solid-State and Inorganic Molecular Chemistry of the CNRS-University of Rennes, and from 2006 to 2009, the Head of the Theoretical Inorganic Chemistry group of the Institute of Chemical Sciences from the CNRS-University of Rennes. He has been Distinguished Visiting Scholar at University of Adelaide, Adelaide, Australia in 1997, and Visiting Scientist at the Max-Planck Institute, Dresden, Germany, in 2005 and 2013. By the end of 2020, he moved to the Laboratory for Innovative Key Materials and Structures (LINK), CNRS – Saint-Gobain – NIMS, National Institute for Materials Science (NIMS), Tsukuba in Japan ( Since March 1, 2023, he is the Head of this laboratory. He is also a member of the French-Australian International Research Project (IRP) CNRS-ANU “MAITAI” focusing on Multiphoton Absorbers in Therapy and Imaging (2021-2025) −
In September 2023, he will join again the Institute of Chemical Sciences from the CNRS-University of Rennes. He was the recipient of the Bronze Medal of the CNRS in 1992 and the French Chemical Society Award in Coordination Chemistry in 1995. He is Member of the French Chemical Society, the American Chemical Society and Fellow of the Royal Society of Chemistry (FRSC). In 2019, he was elected Fellow of the Academia Scientiarium et Artium Europaea (European Academy of Sciences and Arts). He was Guest Editor of several journals (J. Solid State Chemistry (vol. 154, 2000), J. Organomet. Chem. (SI T.P. Fehlner, vol. 721-722, 2012), Polyhedron (SI C. Lapinte, vol. 86, 2015), Struct. Bond. (Ligated transition-metal clusters in solid-state chemistry: The legacy of Marcel Sergent, vol. 180, 2019) and has served on the editorial boards of Polyhedron (2013-present), J. Cluster Science (2013-present), Organometallics (2014-2016), and Inorganics (2018-present). He is Member of the International Board of ISBB Conferences and IMEBORON Conferences. He acted as a Member of the Commission on Crystallography of Materials
of the International Union of Crystallography (2013-2017). His research interests center on the understanding of the chemical bond and the associated physical properties in maingroup and transition-metal inorganic chemistry. He uses a variety of quantum chemical computational tools including Density Functional Theory methods to tackle problems of electron counting, structure, and physical properties of both molecular and solid-state systems. His main recent investigations include (i) The electronic structure and physicchemical properties of large (molecular, nanosized, and solid-state) inorganic transition metal clusters; (ii) The study of the metal-to-carbon bonding and physical properties in polymetallic compounds containing carbon ligands for potential application in electronics and (linear and non-linear) optics; (iii) The electronic and optical properties of organic-boron and metal-boron molecular compounds, and (iv) The understanding of the structural arrangement and the physical (conducting, thermoelectric…) properties of diverse solid-state compounds (borides, boride carbides, nitrides, chalcogenides, intermetallics, etc.). He has published ca. 315 papers (h – index 49), and presented over 200 lectures and seminars at national and international conferences and at research institutions, worldwide. He is or has been involved in several international collaborations (France (D. Astruc on catalytic properties of nanoclusters and nanoparticles; F. Paul, C. Lapinte, J.-R. Hamon on the electronic and optical properties of mixed-valence molecular iron organometallic wires), Australia (M. I. Bruce, P. J. Low, M. I. Humphrey on the electronic and optical properties of mixed-valence molecular ruthenium organometallic wires), China (V. W.-W. Yam, on the optical properties of molecular transition-metal organometallic wires), Germany (T. B. Marder, on the optical properties of molecular boron-containing compounds; Yu. Grin, B. Albert, R. Pöttgen on the structural properties of solids), India (S. Ghosh, on the electronic properties of metallaborane clusters), Ukraine (V. Babizhetskyy on the structural properties of solids), and Japan (D. Berthebaud, T. Mori, on the thermoelectric properties of solids).
