Abstract:
Tetrathiafulvalene (TTF) is one of the most studied heterocyclic molecules of the last
forty years because of its electronic properties and the diversity of its applications. Indeed, the
design of multifunctional materials, based on the motif tetrathiafulvalene (TTF), is a great
challenge for the physical chemistry community. In this context, the objective of this work was
to develop new organosulfur architectures, derived from the tetrathiafulvalene unit (TTF) or its
π-extended derivative (Ex-TTF), conceived for obtaining materials has specific properties.
We present in this manuscript the different strategies considered for the synthesis of
these new molecules associating the tetrathiafulvalene motif with nitrogenous aromatic ligands.
The electronic properties (spectroscopy, cyclic voltammetry) and / or (DFT calculation, X-ray
diffraction) of these compounds have been studied. The complexing properties, in a number of
cases, of these electroactive ligands have also been evaluated by UV-Visible spectroscopy. In
addition, some of the ligands prepared have been the subject of a preliminary study of ion
recognition by spectroscopic route; these architectures show an efficiency in detecting anions
with better selectivity for the fluoride anion.
Finally, these various precursors have been used for the preparation of charge transfer
complexes, radical ion salts and coordination complexes with transition metals. Measurements
of electrical conductivity reveal an insulating behavior for the set of elaborated solids.
