title: [5]Radialene-fused tetrathiafulvalenes exhibiting a simultaneous four- or eight-electron transfer.
abstract: Novel bis- and tris-fused tetrathiafulvalene (TTF) analogs possessing [5]radialene with quintuple 1,3-dithiol-2-ylidene moieties (2-4) were successfully synthesized. Cyclic voltammetry and differential pulse voltammetry revealed that they exhibited a simultaneous four- or eight-electron transfer process. It is suggested that four positive charges are distributed mainly over each of one or two DT[5]radialene units in 2(4+), 3(4+), and 4(8+).
