Structure and Electrochemical Properties of Copper(Ii) Coordination Polymers with Ligands Containing Naphthyl and Anthracyl Fragments

The potentials for the electrochemical reduction of glassy carbon electrodes with deposited copper(II) coordination polymers (CP) containing polypyridine ligands with naphthyl and anthracyl substituents are similar to the potentials of the redox transformations of the corresponding ligands. The difference between the reduction potential of the CP-modified electrode and the potential for the redox transformation of the ligands in solution is greater when the lowest unoccupied molecular orbital of the ligand is predominantly located not on the carbocyclic but rather heterocyclic fragment.
