Polymers functionalized with ion-specific recognition elements
Polymeric compounds containing polymer backbones functionalized with ion-specific recognition elements and methods for the use of these compounds are described herein. The polymeric compounds may contain multiple types of ion-specific recognition elements depending on a specific application. The polymeric compounds can be used to remove ionic species from a solution, for example, in separations applications in which a single or multiple types of ionic species are desired to be removed from the solution.
1. A method of treating an ion imbalance in a subject comprising:
selecting a subject having an elevated level of an ion; and
administering to the subject a block copolymer comprising multiple repeating units, wherein at least one block is uniformly formed from repeating units covalently bound to a calix[4]pyrrole and wherein at least one block is uniformly formed from repeating units covalently bound to a crown ether, and wherein the multiple repeating units are selected from the group consisting of polyacryonitrile, polyacrylate, polystyrene, polyester, polyurethane, polyamide, and a co-polymer thereof.
2. The method of claim 1 , wherein the crown ether is a benzo-15-crown-5 ether.
