摘要:Various embodiments of the present invention relate to a method of preparing coordination polymer crystals, and to the crystals produced thereby. The method includes providing a composition. The composition includes Component (i), a metal-containing compound that is a source of one or more metal ions; Component (ii), a bridging ligand-containing compound that is a source of one or more bridging ligands; Component (iii), a first liquid in which (i) and (ii) are soluble; and Component (iv), a second liquid immiscible with the first liquid. The method includes mixing the composition to form an emulsion. The method also includes maintaining the emulsion for a time sufficient to produce a crystalline coordination polymer. Various embodiments also provide methods of making membranes and membranes made thereby wherein the membrane-forming composition includes the coordination polymer crystals, including methods of making membranes wherein coordination polymer crystals form in the membrane or in the membrane-forming composition before, during, or after curing of the membrane-forming composition. Various embodiments also provide methods of gas separation using the membranes.
