A novel hexakis(tetrathiafulvalene) derivative: synthesis, structure and electrochemical properties

The hexakis(TTF) derivative 3 has been synthesised in 89% yield by six-fold reaction of the thiolate anion of reagent 2 with hexakis(bromomethyl)benzene: the solution electrochemistry of 3 shows sequential formation of the hexa-(radical cation) and the dodecacation species, and spectroelectrochemistry shows interacting radical cations; the X-ray crystal structure of 3 is reported.
