摘要：

It is reported the synthesis of calix[4]-bis-(tribenzo)crown-6 1 consisting of a calix[4]arene fixed in the 1,3-alternate conformation by the 1,3- and 2,4-bridges made of two modified polyether chains in which the three central ethylene links have been replaced by three 1,2-phenylenes. Ligand 1 complex cesium cation and not sodium one. (C) 1999 Elsevier Science Ltd. All rights reserved.
