摘要：

The effects of the molecular structure of isomeric aminonaphthalene sulfonic acids (ANSA) on the EPR and optical spectra of its copolymers with aniline (An) have been investigated. As it has been indicated by EPR and IR-spectroscopy, the higher spin concentration is observed for (1,4-ANSA+An) copolymer when the ortho-para position coupling between ANSA and An takes place. According to UV-spectroscopy of the copolymer films on SnO(2) surface the absorption bands near 400-440 nm (cation-radical species) and 800-900 nm (delocalized conducting electrons) are observed in all the cases. The shape of maxima is depend on ANSA molecular structure.
