摘要:A method of selectively extracting anions from an aqueous solution using an anion encapsulating aggregate formed upon the addition of a solvent, a copper contributor, a hydroxide contributor, a counterion contributor, and pyrazole to an aqueous solution containing the anions, or upon the addition of a solvent, a polymeric chain of [Cu II (μ-OH)(μ-pz)] ∞ and a counterion contributor to the aqueous solution. The aggregates include compounds of the formula cis Cu II x (OR 1 ) y (R 2 pz) z , where R 1 is H or an alkyl group, R 2 is H, or an alkyl group or a charged group, pz is pyrazolate and each of x, y, and z is an integer between about 1 and about 40. In addition, ligand-containing anion encapsulating aggregates can be formed by synthesis with a lig-and-bound pyrazole or by substituting the ligand-bound pyrazole for the pyrazole incorporated in the aggregate.

摘要:A method of selectively extracting anions from an aqueous solution using an anion encapsulating aggregate formed upon the addition of a solvent, a copper contributor, a hydroxide contributor, an optional counterion contributor, and at least one encapsulating anion to an aqueous solution containing the anions, or upon the addition of a solvent, a polymeric chain of [CuII(μ-OH)(μ-ea)]∞ and optionally, a counterion contributor to the aqueous solution. The aggregates include compounds of the formula cis-CuIIx(OR1)y(R2ea)z, where R1 is H or an alkyl group, R2 is H, or an alkyl group or a charged group, ea is an encapsulating anion, and each of x, y, and z is equal to an integer between about 1 and 40, inclusive. In addition, anion encapsulating aggregates can be formed by synthesis with alternate encapsulating anions by substituting alternate encapsulating anions for the encapsulating anion incorporated in the aggregate.
