Structure and Electronic Properties of Polyaniline

Degree of protonation and oxidation dependence of the spin-lattice relaxation time T 1 ( 1 H-NMR), 13 C-NMR spectrum, FT-IR spectrum for polyaniline are presented. It is concluded that benzoid rings in the chain are transformed into quinoid rings by oxidation, and in oxidized polyaniline the degree of localization of electrons is dominated by the degree of protonation.
