摘要
Syntheses of double-calix[4]arenes, doubly-crowned calix[4]arenes, and double-calix-crowns have been achieved by reacting p-tert-butylcalix[4]arene or a new mesitol based calix[4]arene with various polyethylene glycol ditosylates in the presence of potassium carbonate in refluxing acetonitrile. Depending on the nature of the ditosylate and on the reaction times are differently obtained calixarene ligands. The complexation properties toward alkali cations are presented for the double-calix-crown derived of p-tert-butylcalix[4]arene.
