Synthesis of the Water-Soluble, Electrically Conducting Poly (5-Aminonaphthalene-2-sulfonic Acid)

Abstract

Poly(5-aminonaphthalene-2-sulfonic acid) 2 can be prepared by oxidative polymerisation of 5- or 8-aminonapthalene-2-sulfonic acid (1a, 1b) with Na2S2O8 or KIO4. This polymer is water soluble, electrically conducting and fluorescent.
