Using the reactivity of the carbonyl groups of 4,5‐diformyl‐1,3‐dithiol‐2‐ylidene‐substituted ethanals or ethanones with ylides or phosphonate anions, highly extended analogs of TTF 1 and 2 were synthesized by Wittig or Wittig−Horner reactions. Their excellent π‐donor properties, as well as the possibility of obtaining polycationic states, were confirmed by cyclic voltammetry. The structural study of cation‐radical salt 1bβγ·PF 6 reveals a two‐dimensional network in the solid state.
