摘要： The disclosure provides methods to produce ultrathin metal nanowires and methods to produce ultrathin copper elongated nanostructures. Also claimed are the metal nanowires produced by these methods, and the use of the metal nanowires as transparent conductors. The claimed method comprises the steps of: a) forming a reaction mixture comprising a silane-based reducing agent, a copper metal salt and a surface ligand, wherein the surface ligand may also be a solvent; and b) heating and maintaining the reaction mixture at an elevated temperature between 1 to 48 hours with or without stirring. Examples for copper metal salts are Cul, CuBr, CuCI, CuF, CuSCN, CuCI2, CuBr2, CuF2, Cu(OH)2, Cu-D-gluconate, CuMo04, Cu(N03)2, Cu(Clo4) 2, CuP207, CuSe03, CuS04, Cu-tartrate, Cu(BF4)2, Cu(NH3) 4SO4, and including any hydrates of the foregoing. Examples for silane-based reducing agents are: trietylsilane, trimethylsilane, triisopropylsilane, triphenylsilane, tri-n-propylsilane, tri-n-hexylsilane, triethoxysilane, tris(trimethylsiloxy)silane, tris(trimethylsilyl)silane, di-tert- butylmethylsilane, diethylmethylsilane, diisopropylchlorosilane, dimethylchlorosilane, dimethylethoxysilane, diphenylmethylsilane, ethyldimethylsilane, ethyldichlorosilane, methyldichlorosilane, methyldiethoxysilane, octadecyldimethylsilane, phenyldimethylsilane, phenylmethylchlorosilane, l,l,4,4-tetramethyl-l,4-disilabutane, trichlorosilane, dimethylsilane, di-tert-butylsilane, dichlorosilane, diethylsilane, diphenylsilane, phenylmethylsilane, n-hexylsilane, n- octadecylsilane, n-octylsilane, and phenylsilane. Examples for surface ligands are oleylamine, trioctylphosphine oxide, oleic acid, 1,2-hexadecanediol, trioctylphosphine, or any combination of the foregoing. Examples for devices where said transparent conductors are of use are: LCD display, a LED display, a photovoltaic device, a touch panel, a solar panel, a light emitting diode (LED), an organic light emitting diode (OLED), an OLED display, and a electrochromic window.
