  Eight proton di-ionisable diacid conformers of nano-baskets including 25,26-di(carboxymethoxy)calix[4]arene-crown-3, -crown-4, -crown-5 and -crown-6 in the cone conformation have been synthesised and shown to extract lanthanide cations effectively. Their selectivities were greatly influenced by the acidity of the solution and the conformations of the calix-crown. The extraction loading was improved by having the p-tert-butyl-moiety in the upper rim. The scaffold bearing the crown-4 ether moiety showed the least loading, while scaffolds with crown-3- and crown-5-ether moieties had the best selectivities.

• Electrochemical Study of Structural Effects in Complexation of Nano-baskets: Calix[4]-1,2-crown-3, -crown-4, -crown-5, -crown-6
  作者：Bahram Mokhtari、Kobra Pourabdollah

  DOI：10.1080/15533174.2012.680131

  日期：2012.9.1

  Eight nano-baskets of calix[4]arene-1,2-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 macrocyclic complexes by voltammetric behaviors of two acidic moieties in each scaffold during complexation of crown ether ring. The results revealed that by increasing the binding ability of macrocycle and cation, the anodic oxidation peak of carboxylic acids was decreased. Moreover, the voltammetric traces of low energy complexes did not affected by encapsulated cations in the coordination space of crown ether.
