  • Electromechanical reduction of a diazonium salt to modify the surface of a metallic material
    Patent number: 7364648
    Abstract: The invention concerns a metal material with a surface which is modified by bonding an aromatic group, optionally substituted by a functional group, on the surface. In one embodiment, an aromatic group is attached to the surface by electrochemical reduction of a diazonium salt containing the aromatic group. The metal material is brought into contact with a solution of the diazonium salt in a solvent and negatively polarized relative to an anode that is also in contact with the solution. A carbon-metal bond of the covalent type is formed.
    Type: Grant

  • Process for the electrochemical production of a carbon-containing material whose surface is modified with organic groups, and use of the modified material
    Patent number: 7229668
    Abstract: Methods for producing by electrochemical reduction a carbon-containing material with its surface modified by organic groups, in particular functionalized organic groups. Certain embodiments of the methods include contacting the carbon-containing material with an organic diazonium salt in solvent, optionally in the presence of an electrolyte and negatively polarizing the carbon-containing material relative to an anode also in contact with an electrolytic solution separate from said diazonium salt solution, wherein the electrochemical reduction is carried out on an organic diazonium salt in protic solvent in an acid medium. Carbon-containing materials with a surface modified by organic groups and the use of these modified materials, for example for producing composite materials or for fixing molecules of biological interest, are taught.
