A new class of pyrylium salts and process for the manufacture, as well as the use of the new pyrylium salts as polycondensation components for a new class of polypyridinium salts and a new class of conducting polypyridinium salts manufactured by doping the polypyridinium salts with a conducting dopant is described. The new polypyridinium salts and their conducting doped analogs according to this invention are stable positively charged polymers resistant to base attack and are distinguished by water insolubility making them ideally suited as a metal anti-corrosion coating, stable in basic media making them ideally suited for separation membranes for anions, and as excellent, thermally and chemically stable conducting polymers when doped ideally suited for making electrically conducting materials and as redox catalysts.
