Mobile ions can be introduced thereby increasing the conductivity, with a limiting operating temperature range of 200°–250°C. Conductivity can be increased with the formation of conjugatd double bonds. Polymeric compounds may be synthesized with metallocyclic groups, where an atom of metal is bound to nitrogen atoms in a heterocyclic system in the basic chain of conjugation of the macromolecule. Here phtalocyanimes possess the greatest thermal stability. Lastly there are semiconducting polymers with conjugated double bonds containing hetero‐atoms in the principle chain, having unpaired electrons of oxygen and nitrogen.
