Oligothiophenes molecular wires

Oligothiophenes are good candidates for conductive molecular wires. The thiophene-2,5-diyl moiety has been used as a molecular wire unit for energy and elec-... 

In our study, the oligothiophenes, which can be easily dimerized by electrochemical oxidation, were used as not only molecular wire but also coupling elements. Phosphorus(V)porphyrin, which have strong oxidizing powers and are stable to the electrochemical oxidation, were used as the photosensitizer. Since the phosphorus(V)-...
