  Stilbene-bridged 1,3-alternate calix[4]arene crown ether for selective alkali ion extraction

  摘要：

  A series of stilbene-bridged calix[4]arenes was synthesized through an intramolecular reductive McMurry coupling of hisbenzaldehyde calix[4]arene in high yields. Tetra- and pentaethylene glycol chains were tethered to the phenolic groups of calix[4]arene to form stilbene-bridged calix[4]arene crown-5 and crown-6, respectively. The presence of stilbene bridge over the calix[4]arene rim effectively prevented the connection of the polyether chains in the cone conformation resulting in the exclusive formation of 1,3-alternate stilbene-bridged calix[4]arene crown product. Compared to the cone analogues, the 1,3-alternate calix[4]arene crown ethers showed a greater extraction ability and selectivity toward Cs+. (c) 2007 Published by Elsevier Ltd.
