Abstract
Abstract The dimethylsilylene moiety was almost eliminated during the chemical polymerization of dimethyl-bis(2-thienyl)silane (MTS) with iron(III) chloride. On the other hand, the polymerization of diethoxy-bis(2-thienyl)silane (EOTS) with iron(III) chloride produced poly[diethoxy-bis(2-thienyl)silane] without eliminating the diethoxysilylene moiety. Poly-EOTS was doped with iodine without causing irreversible reaction. Electrical conductivity was 2.1×10 −1 Scm −1 . Diethoxy-bis[2-(3-dodecylthienyl)]silane (EODTS) was also polymerized with iron(III) chloride and poly-EODTS was soluble in organic solvents. The ESCA analysis of its film indicated that it contained silicon as well as sulfur. Poly[dioctyloxy-bis(2-thienyl)silane] (poly-OOTS) was prepared by the coupling of dichlorodioctyloxysilane with 5,5′-dilithio-2,2′-bithiophene and its spectra were measured. These results indicate that the introduction of alkoxy groups on silicon atoms leads to high durability to oxidation and reduction without decreasing mobility of charge-carriers along the polymer chain.
