Abstract
The first 1,3-alternate calix[4]arene-bis(crown-6-ethers) with a proton-ion izable group located in front of one crown ether cavity are synthesized. Co mpared with an analog that has no proton-ionizable group, the two new ligan ds possess markedly higher Cs+ extraction efficiency. (C) 2000 Elsevier Sci ence Ltd. All rights reserved.
