Abstract

This invention relates to materials and methods for iodine capture from a variety of sources and media, and at water/organic solvent interfaces.

Claims (49)

1 . A compound of Formula (II):

wherein:

m is 0, 1, 2, 3, or 4;

n is 0, 1, 2, 3 or 4;

a is 0, 1 or 2;

Ar 1 is optionally substituted aryl, or optionally substituted heteroaryl; and

R 1 is an electron withdrawing group, or an electron donating group.

2 . The compound of claim 1 , wherein Ar 1 is selected from the group consisting of:

3 . The compound of claim 1 , wherein the compound of Formula (II) is a compound of Formula (II-a):

wherein:

m is 0, 1, 2, 3, or 4; and

Ar 1 is optionally substituted aryl, or optionally substituted heteroaryl.

4 . The compound of claim 3 , wherein Ar 1 is selected from the group consisting of:

5 . The compound of claim 1 , wherein the compound of Formula (II) is a compound of Formula (II-b):

wherein:

Ar 1 is optionally substituted aryl, or optionally substituted heteroaryl.

6 . The compound of claim 5 , wherein Ar 1 is selected from the group consisting of:

7 . The compound of claim 1 , wherein the compound of Formula (II) is selected from the group consisting of:

8 . A method for removing a material from a medium, the method comprising:

providing a medium comprising a material;

contacting the medium with a compound of claim 1 ;

capturing the material with the compound; and

removing the compound that contains the captured material from the medium.

9 . The method of claim 8 , further comprising removing the captured material from the compound.

10 . The method of claim 8 , wherein the material is non-radioactive molecular iodine (I 2 ), radioactive molecular iodine (I 2 ), or combination thereof.

11 . The method of claim 8 , wherein the medium is aqueous medium, organic medium, or combination thereof.

12 . A method for removing a material from a medium, the method comprising:

providing a medium comprising a material;

contacting the medium with a compound of claim 7 ;

capturing the material with the compound; and

removing the compound that contains the captured material from the medium.

13 . The method of claim 12 , further comprising removing the captured material from the compound.

14 . The method of claim 12 , wherein the material is non-radioactive molecular iodine (I 2 ), radioactive molecular iodine (I 2 ), or combination thereof.

15 . The method of claim 12 , wherein the medium is aqueous medium, organic medium, or combination thereof.

16 . A method of making a compound of claim 1 , the method comprising:

reacting a compound of Formula (I) with a compound of Formula (VII) to obtain a compound of Formula (II) of claim 1 ,

wherein the compound of Formula (I) is:

wherein:

m is 0, 1, 2, 3, or 4;

n is 0, 1, 2, 3 or 4; and

R 1 is an electron withdrawing group, or an electron donating group; and

wherein the compound of Formula (VII) is:

wherein,

Ar 1 is optionally substituted aryl, or optionally substituted heteroaryl; and

a is 0, 1 or 2.

17 . An article of manufacture comprising a compound of claim 1 .

18 . The article of manufacture of claim 17 , wherein the article of manufacture is a paint, a primer, a coating, or a coating material.

19 . A composition comprising a compound of claim 1 .

20 . The composition of claim 19 , wherein the compound is selected from the group consisting of:
