Novel immobilized calixarenes and related compounds and process for their production
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.

10 . A process according to claim 5 in which the one or more elements is silicon.
11 . A process for immobilizing a calixarene or a calixarene-related compound on a substrate containing one or more metallic or non-metallic oxides comprising;
(a) reacting a polyhalide or polyalkoxide of one or more elements selected from silicon, tungsten, niobium, titanium, zirconium, manganese, vanadium, chromium, tantalum, aluminum, phosphorus, boron, rhodium, molybdenum, germanium, copper, platinum and iron with the calixarene or calixarene-related compound, forming a modified calixarene or calixarene-related compound; and (b) contacting the modified calixarene or calixarene-related compound with the substrate so as to immobilize the calixarene or calixarene-related compound to the substrate through at least one phenolic oxygen linkage.
12 . A process according to claim 11 in which the one or more elements are selected from silicon, tungsten, niobium, titanium, zirconium, manganese, vanadium, chromium, tantalum, aluminum, phosphorus, boron, rhodium, molybdenum, germanium, copper, platinum and iron.
