Zusammenfassung:	Dimeric and trimeric tetrathiafulvalene (TTF) derivatives possessing carbonyl groups in the spacer ( 1, 2) and dimeric TTF derivatives and tetrathiapentalene (TTP) derivatives possessing ester groups in the spacer ( 3, 4) have been synthesized. Cyclic voltammogram of 1– 3 exhibits two pairs of redox waves. No significant shift of redox potentials was observed as increase of the TTF units. Cyclic voltammogram of 4 shows four pairs of two-electron redox waves. The E 1 / 2 2 − E 1 / 2 1 value of 4 is larger than that of the corresponding monomer and the first redox wave is slightly broad, suggesting small intramolecular interaction between two TTP units in the oxidation states.
