In-situ Attainment of Paramagnetic Behaviour of Poly(Amino-Acetanalide) during Synthesis

Abstract

Polyaniline and its derivatives have gained significant interest because of their unique electronic property, simple synthesis process and their environmental stability. We report on the cerium (IV) ammonium nitrate mediated synthesis of poly (amino-acetanilide), PAA, using an interfacial polymerization technique in which PAA serves as a guest of the cerium (III) ion, a paramagnetic species produced during the synthesis condition. The cerium (III) ionic species bonded with the chain nitrogen of the PAA and the supramolecular system show the paramagnetic behavior throughout the experimental temperature range 400-1.9 K.
