ABSTRACT: The association within one molecule ofcalixarene and crown ether moieties leads toligands with new complexing properties. In particular,calixarene bis(crown-6) and some of itsderivatives have been shown to be highly selectiveextractants for caesium ions. This review presents thebackground of the study and the results of crystalstructure determinations and molecular modellingcalculations performed during the investigation of twomolecular families, the bis(crown ether) and theazobenzocrown derivatives of calixarene.
