Separation and Purification of Calixarenes

1 f Calixarenes carrying phosphoryl groups on the lower rim have been separated by this technique, and chiral calix[4]arenes have been resolved by the use of enantioselective columns. Still another separation technique that has been occasionally used is capillary zone electrophoresis, e.g. for the separation of p-sulfonatocalixarenes. Most recently, calixarenes have been separated on a
