Abstract |
Eight nano-baskets of cone calix[4]arene-crown-3, -crown-4, -crown-5, -crown-6 were synthesized and
their binding abilities towards alkali and alkaline earth metals as well as some lanthanides were studied
using differential pulse voltammetry. The novelty of this study was investigation of those nano-basket
complexes by voltammetric behaviors of two acidic moieties in each scaffold during complexation of crown
ether ring. Their voltammetric behaviors were closely related to the complex formation by entrapment of
cation into crown ether cavity and ion-dipole interaction between cation and acidic moieties in nanobaskets.
The results revealed the selective changes in voltammetric behavior of synthesized scaffolds toward
the cations. By increasing the binding ability of macrocycle and cation, the anodic oxidation peak of
carboxylic acids was decreased. It was shown that the voltammetric traces of low energy complexes did not
affected by encapsulated cations in the coordination space of crown ether and they showed no voltammetric
behavior.
