Synthesis, structure and properties of a novel trisulfide double-bridged TTF dimer

We have synthesized novel trisulfide-bridged tetrathiafulvalene (TTF) dimer molecule in which two TTF moieties are connected to each other by two trisulfide chains. X-Ray crystal structure analysis reveals that the molecule has a unique cyclophane-like U-shape structure. The structure of the ClO4 salt is also described.
