A series of the longest class of oligothiophenes extended at intervals of seven thiophene units from the 6-mer up to the 48-mer has been synthesized. It is estimated that the molecular length of the longest 48-mer reaches approximately 18.6 nm. The systematic studies of the oligothiophenes have provided valuable information on the optical and conductive properties of α-conjugated thiophene systems: an effective conjugation length extends to 20-30 thiophene units, and the active charge carrier species are both π-dimers and chain dimers. The efficient molecular-wire behaviors of oligothiophenes have been demonstrated by photoinduced electron and/or energy transfer characteristics of the fullerene-linked dyad and triad systems. The successful application of these systems to a photovoltaic molecular device is also described.
