Abstract

Structurally well-defined oligothiophenes have attracted much interest in view of their potential for molecular wires. Thus the investigation into electronic and electrical single-molecular properties of oligothiophenes is essential for forthcoming single-molecular electronics. However, it is generally recognized that the elongation of pai-conjugated oligomeric chains induces strong intermolecular pai-pai interactions as well as pai-dimer formation, which result in encounter the difficulty of elucidating the single-molecular properties. In this regard, we have previously reported the synthesis of 2,7-dioctylfluorenene annelated cyclopenta[c]thiophene based oligomers. Spectroscopic data revealed that their effective conjugation is maintained and that formation of pai-dimers is perfectly prohibited. These promising properties have prompted us to investigate the introduction of sulfur terminal groups in expectation of measuring single-molecular properties. In this presentation, we report on the synthesis and electronic properties of oligothiophenes possessing bulky insulating groups at all the repeating units and sulfur anchoring groups at both terminal positions.
