Poly[di(2-thiophenyl)carborane]s: conducting polymers with high electrochemical and thermal resistance.

The synthesis, X-ray structure and electropolymerization of three new carbon-carbon linked di(2-thiophenyl)carboranes (, and ) are reported; the resulting polymers bearing icosahedral ortho-, meta- or para-carborane clusters show high thermal and electrochemical stabilities in comparison with unsubstituted polythiophene; the ortho-carborane-containing polymer has the highest conductivity of the new materials.
