<p>The invention provides a tetrazole-containing polymer of intrinsic microporosity comprising (10) or more subunits, wherein one or more of the subunits comprise one or more tetrazolyl moieties. In one embodiment, a polymer of intrinsic microporosity (PIM-1 ) was modified using a "click chemistry" [2 + 3] cycloaddition reaction with sodium azide and zinc chloride to yield new PIMs containing tetrazole units. Polymers of the present invention are useful as high-performance materials for membrane-based gas separation, materials for ion exchange resins, materials for chelating resins, materials for superabsorbents, materials for ion conductive matrixes, materials for catalyst supports or materials for nanoparticle stabilizers.</p> |
