Syntheses and Electrical Properties of Organosilicon Polymers Containing Thiophene and Anthraquinone Units

Article abstract of DOI:10.1246/bcsj.66.1244

Organosilicon polymers containing thiophene and anthraquinone units in the main chain were synthesized using palladium catalyst.These polymers were soluble and showed a small UV absorption change by the substituents on the silicon atom.Some of the polymers exhibit cation doping (n-doping) by the electrochemical reduction, and this doping process seemed to depend on the kinds of substituents on silicon atom.These polymers showed electrical conductivity of 3 * 10^-5 S cm^1- when doped with sodium naphthalenide.
