Didodecylsexithiophene—A Model Compound for the Formation and Characterization of Charge Carriers in Conjugated Chains

This is the authors' abstract. We don't add key points for this paper.

The four redox steps between the dication and the dianion of didodecylsexithiophene 1, a soluble oligothiophene with defined structure and chain length, were studied by a combination of in situ UV/VIS/near IR and ESR spectroscopy. The reversible dimerization 1˙+ → (1) provides a new description of the doping behavior of polythiophenes and conducting polymers in general.
