Abstract
Immobilized calixarenes and calixarene-related compounds are produced by a process comprising either: (a) contacting the calixarene or calixarene-related compound with a substrate containing one or more metallic or non-metallic oxides that has been surface modified by reaction with one or more polyhalides and/or polyalkoxides of an element capable of forming a stable aryloxide species with the substrate, or (b) reaction of such a substrate with a calixarene or calixarene-related compound that has been previously modified or derivatized by reaction with said polyhalides and/or polyalkoxides.
Claims6
A composition comprising a calixarene or a calixarene-related compound immobilized on a substrate containing one or more metallic or non-metallic oxides via bonding between one or more polyvalent metallic or non-metallic atoms and at least one phenolic oxygen atom of the calixarene.
