A new cyclic tetrathiafulvalene (TTF) tetramer 1 was synthesized. The cyclic voltammogram of 1 consists of four pairs of two-electron redox waves. UV-vis-NIR spectra of the oxidative species of 1 suggest that 1(2+), 1(4+), and 1(6+) possibly adopt two pairs of dimeric TTF structures that interact with each other through the so-called side-by-side interaction.
