Abstract

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.

Claims (26)

1. A polymeric compound comprising the following calix[4]pyrrole monomeric unit:

2. The polymeric compound of claim 1 , further comprising the following methyl methacrylate monomeric unit:

3. The polymeric compound of claim 2 , further comprising the following benzo-15-crown-5 ether monomeric unit:

4. The polymeric compound of claim 1 , wherein the polymeric compound is further functionalized with a zwitterion-specific recognition element.

5. A method of removing an ionic species from a solution comprising adding a polymeric compound comprising the following calix[4]pyrrole monomeric unit:

to the ionic species in the solution.

6. The method of claim 5 , wherein the ionic species is a cationic species.

7. The method of claim 5 , wherein the ionic species is an anionic species.

8. The method of claim 5 , wherein the ionic species is a zwitterionic species.

9. The method of claim 5 , wherein the ionic species comprises a mixture of two or more ionic species selected from cations, anions, and zwitterions.

10. The method of claim 5 , wherein the polymeric compound further comprises the following methyl methacrylate monomeric unit:

11. The method of claim 10 , wherein the polymeric compound further comprises the following benzo-15-crown-5 ether monomeric unit:

12. The method of claim 5 , wherein the polymeric compound is further functionalized with a zwitterion-specific recognition element.

13. A method of treating an ion imbalance in a subject comprising:

selecting a subject with or suspected of having an elevated level of an ion; and

administering to the subject a polymeric compound comprising the following calix[4]pyrrole monomeric unit:

14. The method of claim 13 , wherein the ion is a cation.

15. The method of claim 13 , wherein the ion is an anion.

16. The method of claim 13 , wherein the ion is a zwitterion.

17. The method of claim 13 , wherein the ion comprises a mixture of two or more ionic species selected from cations, anions, and zwitterions.

18. The method of claim 13 , wherein the polymeric compound further comprises the following methyl methacrylate monomeric unit:

19. The method of claim 18 , wherein the polymeric compound further comprises the following benzo-15-crown-5 ether monomeric unit:

20. The method of claim 13 , wherein the polymeric compound is further functionalized with a zwitterion-specific recognition element.

21. The polymeric compound of claim 1 , wherein the polymeric compound is a homopolymer of one of the following calix[4]pyrrole monomeric units:

22. The method of claim 5 , wherein the polymeric compound is a homopolymer of one of the following calix[4]pyrrole monomeric units:

23. The method of claim 13 , wherein the polymeric compound is a homopolymer of one of the following calix[4]pyrrole monomeric units:
