Synthesis, Structure and Redox Property of a New Tetrathiafulvalene Based Macrocyclic Compound

A new macrocyclic compound based on tetrathiafulvalene (TTF) and 2,5-bis(chloromethyl)- thiophene was synthesized and structurally characterized by elemental analysis, 1H NMR spectrum, MALDI-TOF MS and X-ray single-crystal diffraction analysis. The crystal of compound 1 belongs to monoclinic space group P2(1)/n with cell parameters a＝0.97220(19) nm, b＝1.2366(3) nm, c＝1.6051(3) nm, β＝95.41(3)°, V＝1.9211(7) nm3, Z＝2, Dc＝1.621 g/cm3, F(000)＝960, μ＝1.032 mm－1, R＝0.0333, and wR＝0.1000 [I＞2σ(I)]. Moreover, compound 1 displayed two couples of cathodic and anodic peaks in the cyclic voltammogram, and the redox processes are irreversible.
