The synthesis of oligomeric homologs of BEDT-TTF and TTC(n)-TTF posses
sing three TTF subunits in full pi-conjugation was accomplished starti
ng from soluble dithiones. Cyclic voltammetric investigation revealed
the formation of a hexacation upon oxidation. Details are discussed in
comparison to suitable model compounds. Charge-transfer complexes and
radical-cation salts derived from the new donors were investigated by
electrical conductivity measurements.
