Method For The Functionalisation Of Metal Nanowires And The Production Of Electrodes

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.
