Abstract

Intercalative polymerization of aniline, pyrrole and 2,2’-bithiophene in vanadium oxide xerogels results in electrically conductive novel materials which are composed of alternating monolayers of metal-oxide and conductive polymers. The driving force for this intercalation is redox chemistry. The conductivity type in these materials is a function of the polymer/V2O5 xerogel ratio. Low ratios result in xerogel-based charge transport, while high ratios favor polymer-based charge transport properties. Chemical, spectroscopic and electrical data on the intercalative polymerization products of aniline, pyrrole and 2,2’-bithiophene with V2O5 xerogels are presented.

[15] Although not critical for the data in curve (B), the data in curve (A) must be corrected for the contribution of the gold thermopower. This correction will shift the data by a small amount (ca. 1–2 μV depending on the temperature) toward more positive values, thus bringing the entire curve (A) on the positive scale of the plot.Google Scholar
