Abstract:
The dependence of the conductivity in thin films of polymer complexes of nickel with N$_4$ ligands with macrocyclic and chelate structure on the doping level has been studied by the electrochemical in-situ conductance method. The electrochemical conductivity window of polymers depends on the structure of the monomers and approached 1.2 V for the macrocyclic complex. Electrochemical doping changes the electrical resistance of the investigated materials by 4 orders of magnitude.
