This work focuses on two main topics: electroactive ligands and helical chirality in tetrathiafulvalenes, with the development of TTF-triazoles, TTF-bis (bis-oxazolines) and TTF-helicenes. The synthesis of TTF-triazoles via two click chemistry strategies, CuAAC and RuAAC, yields a library of mono- and polydentate electroactive ligands, the crystal structures as well as theoretical study for the TTF-mono-triazoles being reported within. The ability of the above mentioned systems to act as ligands was tested and, consequently, new transition metal complexes were obtained and characterized. Also, we have developed the synthesis of a chiral TTF-bis(bis-oxazoline) and studied its coordination and activity in enantioselective homogeneous catalysis reactions. In a second part, we present the synthesis of new helical precursors: the TTF-helicenes, including experimental and theoretical studies of their chiroptical properties. More specifically, a circular dichroism study depending on the redox state of the TTF unit highlights a phenomenon of chiroptical switch for these compounds. Finally, a new perspective emerged with the synthesis and characterization of two platinum (II) (bipyridine) (helicenedithiolate) complexes, the first helical dithiolenes complexes.
