Provided is a method of extracting a metal ion, which comprises contacting a compound of formula (RSiO)with a source of the metal ion, whereby the compound and the metal ion form a complex, wherein each R is independently Calkyl, and n is 3-10. 1. A method of extracting a metal ion from a source , the method comprising:{'sub': 2', 'n, 'contacting a compound of formula (RSiO)with the metal ion in the source, whereby the compound and the metal ion form a complex;'}{'sub': '1-10', 'wherein each R is independently selected from Calkyl, and n is 3-10.'}2. The method of claim 1 , wherein the metal ion is a lithium ion.3. The method of claim 1 , wherein the source comprises the metal ion and a counterion selected from the group consisting of F claim 1 , Cl claim 1 , Br claim 1 , I claim 1 , HSO4 claim 1 , SO claim 1 , HCO claim 1 , CO claim 1 , B(OH) claim 1 , BO claim 1 , BO claim 1 , BO claim 1 , NO claim 1 , HPO claim 1 , HPO claim 1 , PO claim 1 , and combinations thereof.5. The method of claim 1 , wherein the Rgroups are the same.7. The method of claim 1 , wherein the source of the metal ion comprises an aqueous solution.8. The method of claim 1 , wherein the source of the metal ion comprises seawater.9. The method of claim 1 , wherein the pH of the source of the metal ion is 1 to 12.10. The method of claim 1 , wherein the pH of the source of the metal ion is 2 to 4.11. The method of claim 1 , further comprising pre-treating the source of the metal ion before contacting the compound of formula (I) with the source.13. The method of claim 1 , further comprising isolating the metal ion from the complex.14. The method of claim 1 , further comprising distilling the compound.15. The method of claim 1 , wherein the concentration of the metal ion in the source is about 1×10M to about 1×10M.16. The method of claim 1 , wherein the concentration of the metal ion in the source is about 1×10M to about 1×10M.17. The method of claim 1 , wherein the concentration of the metal ion in ...
