As a new tetrathiafulvalene (TTF)-based donor molecule were synthesized spirocarbon and germanium compounds substituted with two tetrathiafulvalenyldithiolate groups. The redox processes were composed of two pairs of broad and reversible waves, each of which involves two electron transfer. The radical cations or bis(radical cation)'s generated by one- or two-electron oxidation were characterized by ESR.
