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.
