Abstract

Palladium-catalyzed polycondensation between N, N′-dichloro-p-benzoquinone diimines and diorganometallic aromatic compounds provides a new route for the synthesis of polyanilines. A polymer composed of dimethyl-p-benzoquinone diimine and thiophene units has an electrical conductivity of about 1 S·cm-1 at room temperature, and the temperature dependence of the electrical conductivity follows a variable-range-hopping-type equation.
