Highly extended π-donors 1-3 have been obtained through twofold or fourfold Wittig olefinations of polyformyl tetrathiafulvalenes with P-ylids bearing the 1,3-dithiol-2-ylidene moiety. Their powerful π-donor properties as well as their ability to generate cation-radical salts of mixed valency have been evaluated by both classical and thin layer cyclic voltammetry. Such extended π-donors prove to be planar in the neutral state, with very short intramolecular S...S distances, as demonstrated by the X-ray diffraction study of the model compound 16b. Such extended sulfur-rich tetrathiafulvalene derivatives are prone to generate highly dimensional materials as demonstrated in the case of the 3a.ClO4 cation-radical salt which presents a unique type of two-dimensional network in the solid-state.
