Abstract
New thiophene-containing polyazomethines have been synthesized by chem ical polymerization in the presence of either copperII underbar perchl orate or its ammonia complex. The monomers were prepared by condensati on of 2-thiophenecarboxyaldehyde with aromatic diamines. The structure of both monomers and polymers has been studied by FT-IR, NMR, ESR and X-ray spectroscopies. The polymers, in oxidized form, contain from 0. 5 up to 2.0 perchlorate anions per unit dependending on the reaction c onditions and nature of oxidizing agent. Their electrical conductiviti es varied in the range 10(-2) - 10(-5) S/cm.
