1. A process for the functionalization of metal nanowires comprising a step of formation of a self-assembled monomolecular layer over at least a portion of their external surface, wherein:
the nanowires are made of a metal chosen from silver (Ag), gold (Au), copper (Cu), platinum (Pt), palladium (Pd), nickel (Ni), cobalt (Co), rhodium (Rh), iridium (Ir), ruthenium (Ru) and iron (Fe), and in that:
the self-assembled monomolecular layer is obtained by reaction of a compound of following formula (I):
R1—Zn—R2 =Formula (I)in which:
Z represents a sulfur or selenium atom, n=1 or 2, R1 represents a hydrogen atom, an acyl group or a saturated or unsaturated and linear, branched or cyclic hydrocarbon group comprising from 1 to 100 atoms and optionally comprising one or more heteroatoms; R2 represents:either an electron-withdrawing group chosen from a saturated or unsaturated, aromatic or nonaromatic and linear, branched or cyclic hydrocarbon group completely or partially substituted by nitro, trifluoromethyl, cyano, amide, ester, carboxylic acid, halide or 2-dicyanomethylene-3-cyano-2,5-dihydrofuran groups and/or comprising at least one fluorine atom,or an electron-donating group chosen from a linear or branched, cyclic and/or aromatic, hydrocarbon group completely or partially substituted by alkoxy, amine or thioether groups, and
R1 and R2 can be identical or different. |
