Method of modifying a surface (S) of a solid conductive material, comprises (E) applying a negative potential difference, between the surface (S) and a surface (S1) of another solid conductive material laid opposite to the surface (S), and contacting the surface (S) with a liquid medium comprising, in solution, triarylamine compounds (I), simultaneously with the application of the potential difference, where subjecting (I) to electromagnetic radiation for partly converting at least triarylammonium radicals. Method of modifying a surface (S) of a solid conductive material, comprises (E) applying a negative potential difference, between the surface (S) and a surface (S1) of another solid conductive material laid opposite to the surface (S), and contacting the surface (S) with a liquid medium comprising, in solution, triarylamine compounds of formula (I), simultaneously with the application of the potential difference, where subjecting (I) to electromagnetic radiation for partly converting at least triarylammonium radicals. -A1-, -A2- : a single covalent bond, -O- (preferred), -S-, -NH- or -NR3-; R1-R3 : aryl group, preferably a benzyl group, 4-30C hydrocarbon chain or a polyethylene glycol chain; R : a terminating group, which is preferably 1-10C hydrocarbon chain, optionally halogenated and optionally interrupted by one or more heteroatoms of N, O or S. An independent claim is included for conductive materials surface modified by fibrillar supramolecular species based on triarylamine compounds (I) obtainable by the method. [Image]. |
