Oxidative doping and characterization of electrically conductive poly(undecyl bithiophene)s with quinone based oxidants.

摘要

Poly(3-alkylthiophene)s have been extensively studied for their attractive properties. They are conductive, processable, and environmentally stable. These polymers exhibit relatively high conductivities in the doped state. In order for these polymers to achieve commercial success, their properties must be well controlled and understood. Structural information regarding the location of the dopant within the polymer will provide valuable information for the systematic design of effective conducting polymers.;This research probed the completely organic charge transfer complex of poly-(3-undecyl-2,2'-bithiophene) and quinones. Charge transfer was been demonstrated by absorption spectroscopies. The location of the dopant in the charge transfer complex has been directly determined by x-ray diffraction. The thermal evolution of a charge transfer complex was also investigated. Since polymer processing often requires thermal treatment, this information is important. If these doped polymers are to gain commercial success, the location and behavior of the dopant must be known.
