Abstract

A nanostructure comprising at least one metal nanowire comprising at least one surface, and at least one surface modifier disposed on the at least one surface, the at least one surface modifier comprising at least one linkage component, at least one nanowire binding moiety bonded to the at least one linkage component, and at least one surface modifying moiety also bonded to the at least one linkage component, where the at least one nanowire binding moiety is bonded to the at least one surface.

Claims

1. A nanostructure comprising:

at least one metal nanowire comprising at least one surface, and

at least one surface modifier disposed on the at least one surface, the at least one surface modifier comprising at least one linkage component, at least one nanowire binding moiety bonded to the at least one linkage component, and at least one surface modifying moiety also bonded to the at least one linkage component,

wherein the at least one nanowire binding moiety is bonded to the at least one surface.

2. The nanostructure of claim 1, wherein the linkage component comprises a hydrocarbon, an organometallic component, a nonmetal, or a neutral moiety.

3. The nanostructure of claim 1, wherein the linkage component does not comprise silicon.

4. The nanostructure of claim 1, wherein the nanowire binding moiety comprises sulfur, nitrogen, phosphorus, or an ionic substance.

5. The nanostructure of claim 1, wherein the nanowire binding moiety comprises at least one fluorine atom.

6. The nanostructure of claim 1, wherein the nanowire binding moiety comprises carbon.

7. The nanostructure of any of claim 1, wherein the nanowire binding moiety binds to the at least one surface through a dipolar bond.

8. The nanostructure of claim 1, wherein the surface modifying moiety comprises an amine group, an epoxy group, a carboxylate group, a trifluoromethyl group, or a thiol group.

9. The nanostructure of claim 1, wherein the surface modifier comprises dodecanethiol.

10. The nanostructure of claim 1, wherein the surface modifier comprises a dithiol.

11. The nanostructure of claim 1, wherein the surface modified comprises a carbene.

12. The nanostructure of claim 1, wherein the surface modifier comprises 1,9-nonanedithiol.

13. The nanostructure of claim 1, wherein the surface modifier comprises 1H,1H,2H,2H-perfluorodecanethiol.

14. The nanostructure of claim 1, wherein the surface modifier comprises 1,3-bis-(2,6-diiso-propyl-phenyl)-imidazolinium chloride.

15. The nanostructure of claim 1, wherein the surface modifier comprises 1,3-bis(1-adamantyl)-imidazolium tetra-fluoroborate.

16. The nanostructure of claim 1, wherein the surface modifier comprises 5,5′

-bis(mercaptomethyl)-2,2′

-bipyridine.

17. A method comprising:

providing at least one metal nanowire comprising at least one surface,

providing at least one surface modifier comprising at least one linkage component, at least one nanowire binding moiety bonded to the at least one linkage component, and at least one surface modifying moiety also bonded to the at least one linkage component, wherein the at least one nanowire binding moiety is bonded to the at least one surface; and

combining the at least one metal nanowire and the at least one surface modifier,

wherein, after combining the at least one nanowire and the at least one surface modifier, the at least one surface modifier is disposed on the at least one surface of the at least metal nanowire.
