Novel immobilized calixarenes and related compounds and process for their production

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 one or more elements selected from silicon, tungsten, niobium, titanium, zirconium, manganese, vanadium, chromium, tantalum, aluminum, phosphorus, boron, rhodium, molybdenum, germanium, copper, platinum or iron, or another element that forms a stable aryloxide with the substrate, forming a modified substrate;
• and
• (b) contacting the modified substrate with a calixarene so as to immobilize the calixarene to the substrate through at least one phenolic oxygen linkage.

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.

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.
