| Summary: | The elaboration of multifunctional materials is a great challenge for the physical chemistry community and the studies of molecular materials exhibiting coexistence or synergy between two or more properties are very active. In particular, molecular compounds displaying electrical conductivity and magnetic interactions are currently the subject of intensive studies. Two approaches are now well-known and are explored. On the one hand, the interactions between mobile electrons of the organic network (π electrons) and localized electrons of paramagnetic transition metal (d electrons) take place through space. On the other hand, these interactions take place through covalent chemical bonds. In the latter, the probability to have significant interaction between π and d electrons is enhanced compared to the first approach. In this perspective article, we will give an overview of the known coordination complexes involving tetrathiafulvalene derivatives as ligands for paramagnetic 3d ions and we will describe their physical properties. If necessary, the coexistence or synergy between electrical conductivity, magnetism and other properties will be highlighted.
This perspective addresses the recent studies and physical properties relating to the π-d tetrathiafulvalene-based systems using the "
through bond
" approach. |

| Bibliography: | Fabrice Pointillart obtained his PhD in physics and chemistry of materials from Pierre et Marie Curie University in 2005, supervised by Prof. Cyrille Train and Prof. Michel Verdaguer. After a two-year period of postdoctoral research at the Department of Chemistry "Ugo Schiff" and INSTM Research Unit, University of Florence with Prof. Roberta Sessoli and Prof. Dante Gatteschi he joined the University of Rennes 1 in 2007, as a CNRS researcher. His current research interests are focused on multifunctional molecular materials based on tetrathiafulvalene ligands combining single molecule magnet behaviour and optical properties. Lahcène Ouahab received his PhD from the University of Rennes 1 in 1985. He was "Maître de conférences" at the University of Constantine (Algeria) and then Associate Professor at the University of Rennes 1 (1988) before getting a permanent position in CNRS as "chargé de recherche" in 1989. He is presently a CNRS director of research and leads the molecular materials research group. He was the director of the "Laboratoire de Chimie du Solide et Inorganique Moléculaire UMR6511-CNRS Université de Rennes 1" during 2004-2006. He was awarded the 1998 prize of the Coordination Chemistry Division, the 2011 Claude Berthault Prize of the "Académie des Sciences" and the 2012 "Grand Prix Pierre Süe" of the French Chemical Society. His fields of research include molecular materials, in particular, multifunctional materials, charge transfer complexes, radical ion salts, organic-inorganic hybrids, polymeric coordination complexes and polyoxometallates. The research activities of Olivier Cador started in 1994 in Bordeaux (France), supervised by the late Professor Olivier Kahn. He mainly focused on the studies of the magnetic properties of systems with various dimensionalities, from nanoparticles to isolated molecules (zero dimensional systems) which show quantum behaviours, and finally to magnets (three dimensional systems) with atypical behaviours. He was recruited by the University de Rennes 1 in 2003 after two postdoctoral research periods in Japan and Italy. Its research is oriented toward multifunctional molecular-based materials. His aim is to develop the synergy between electronic properties, such as magnetism and electrical conductivity, in new molecular edifices based on organic/inorganic networks. Magnetism arises from inorganic molecular bricks, which can be mono- or polynuclear while electronic conductivity comes from the stacking of organic donors. He recently oriented part of his activities on single chain magnets (SCMs) and single molecule magnets (SMMs). Stéphane Golhen obtained his PhD in chemistry in 1997 from the University of Rennes 1. His research activity was mainly devoted to the synthesis and magnetic properties of materials based on polyoxometalates. He got a permanent position as "Maître de Conférences" at the University of Rennes 1 in 1998. His field of interest was then oriented to the synthesis and magnetic and electrical characterizations of materials based on tetrathiafulvalene molecules and structural studies by X-ray diffraction on single crystals.
