Abstract

Methods of producing metal nanowires, compositions, and articles are disclosed. Such methods allow production of metal nanowires with reproducibly uniform diameter and length, even in the presence of catalyst concentration variation. Such metal nanowires are useful for electronics applications.

Claims (9)

1. A method comprising:

providing at least one compound capable of forming at least one halide ion, said compound comprising at least one first atom, at least one halogen atom bonded to the at least one first atom, and at least one aromatic ring comprising at least one carbon atom bonded to the at least one first atom, the at least one first atom comprising at least one of a boron atom, a phosphorus atom, or a silicon atom; and

reducing at least one first metal ion to at least one first metal in the presence of at least one of the at least one compound or the at least one halide ion.

2. The method according to claim 1 , further comprising forming the at least one halide ion by solvolysis of the at least one compound.

3. The method according to claim 1 , wherein the at least one halide ion comprises at least one chloride ion or bromide ion.

4. The method according to claim 1 , wherein the at least one compound is capable of forming at least one carbocation.

5. The method according to claim 1 , wherein the at least one compound comprises at least one of phenylphosphonic dichloride or dichlorophenylborane.

6. The method according to claim 1 , wherein the at least one first metal comprises at least one element from IUPAC Group 11 or at least one coinage metal.

7. The method according to claim 1 , wherein the at least one first metal comprises silver.
