Sažetak
The electrochemical properties of coordination polymers haven’t been extensively studied in the past. However, their electrochemical sensing ability has started to attract more interest recently. This sensing ability generally depends on the particular metal ions and functional organic ligands and is usually revealed by electrochemical methods. The cobalt(II) coordination polymer with 6- aminonicotinate (6-aminopyridine-3-carboxylate) and 1, 2-bis(4-pyridyl)ethane (1, 2-bpe) was prepared under hydrothermal conditions in the mixture of water and ethanol. Its hydrogen-bonded framework is composed of 1-D polymeric {; ; [Co(1, 2- bpe)2(H2O)2]2+}; ; n cations, 6-aminonicotinate anions, nitrate anions and lattice water molecules. In the polymeric {; ; [Co(1, 2- bpe)2(H2O)2]2+}; ; n cation, each cobalt(II) ion is octahedrally coordinated with four pyridine N atoms of various 1, 2-bpe molecules and with two water molecules in trans position. The two adjacent cobalt(II) ions are thus bridged by two 1, 2-bpe molecules, leading to the formation of macrocyclic rings of 22 atoms within the 1-D polymeric cation. This cobalt(II) coordination polymer was studied by cyclic voltammetry and electrochemical impedance spectroscopy to decipher its sensing potential towards the selected cations, anions or organic molecules.
