A Novel Bis(tetrathiafulvalene) Cyclophane: Synthesis, Electrochemical Properties, and X-ray Crystal Structures of the Neutral and Radical Cation Species

Dimeric tetrathiafulvalene (TTF) derivatives have been studied as π-electron donor components of organic conductors. The authors report the synthesis of a novel bis(TTF) cyclophane (see Figure), which possesses a rare “edge-to-face” double linkage of two TTF units, joined by two bridges. The solution electrochemistry of this molecule is described, as are the X-ray structures of the neutral molecule and two cation radical salts.
