摘要： Polymer-metal ion composites and methods are provided for reversibly binding target compounds using such composites. Broadly, the composites comprise an amorphous polymer matrix having a plurality of channels with metal ion-ligand complexes immobilized therein. The composites are formed by polymerizing a polymeric moiety with a metal complex template in the presence of a solvent. The template is formed of a metal ion having a ligand bonded thereto as well as to polymer matrix. The metal ion and ligand are selected to yield a composite having a particular chemical and/or physical environment around the metal sites, depending upon the desired end use. Preferred metal ions include ions of the transition metals. The composites can be contacted with target compounds for reversibly binding the compounds. Exemplary compounds include those selected from the group consisting of oxygen, carbon monoxide, carbon dioxide, compounds having an atom of P, S, or N, and mixtures thereof. The compound can be released from the composites at the desired time and location by heating the compound-containing composite.
