Pyridyldithiafulvenes as precursors of coordination-driven self-assembled redox active macrocycle.

International audienceA novel redox active macrocycle including two vinylogous tetrathiafulvalenes (TTFVs) and two molybdenum tetracarbonyl fragments has been synthezised thanks to the coordination-driven self-assembly of complementary angular derivatives. Pyridyl vinylogous TTFVs have been deliberately elaborated for that purpose, using the oxidative coupling of pyridyldithiafulvenes (DTF). Cyclic voltammetry, IR and NMR spectroscopies, and single-crystal X-ray crystallography of the target molecules have been investigated
