摘要

Macrotetracyclic complexes of nickel(II) containing crown ethers as pendant arms. [Ni(B)](ClO_4)_2, were prepared and characterized. The binding constants of the complexes toward alkali metal ions are relatively small compared with those of free 15-crown-5 or 18-crown-6 and the reduction potentials of the [Ni(B)](ClO_4)_2 in the presence of alkali metal ions shift to the positive direction in the order Li~+> Na~+>K~+>Na~+>Li~+, respectively.
