The present invention relates to a method for producing a layered body comprising at least two layers containing a noble metal in metallic form, which differ from one another in electrical conductivity, porosity, density and/or specific surface unit. The present invention also relates to a layered body obtainable by this method, an electronic component, preferably an electrode, comprising a conductive layer containing a layered body according to the invention, the use of a compound comprising a complex selected from the group consisting of the complexes (COD)Pt[O(CO)CH(CH)CH], (COD)Pt[O(CO)C(CH)CH]and a mixture thereof, for producing a layer containing platinum in metallic form with a defined density, the use of a compound comprising a complex selected from the group consisting of the complexes (COD)Pt[O(CO)CH(CH)CH], (COD)Pt[O(CO)C(CH)CH]and a mixture thereof for producing a layer containing platinum in metallic form having a defined specific surface.

Preparations of noble metal complexes

Platinum complex of the type [L1L2Pt[O(CO)R1]X], wherein L1 and L2 are the same or different monoolefin ligands or together represent a compound L1L2 acting as a diolefin ligand, wherein X is selected from bromide, chloride, iodide, and —O(CO)R2, wherein —O(CO)R1 and —O(CO)R2 are the same or different C6-C18 or C8-C18 non-aromatic monocarboxylic acid groups with the exception of a phenylacetic acid group, or together represent a C8-C18 non-aromatic dicarboxylic acid group —O(CO)R1R2(CO)O—, wherein it is a mononuclear platinum complex where n=1, or wherein, in the event of the presence of L1L2 and/or of —O(CO)R1R2(CO)O—, it may be a polynuclear platinum complex with a whole number n>1.

Platinum complexes

The invention relates to a method for producing a medical electrode, comprising the following steps: (i) providing a substrate; (ii) applying a composition onto the substrate, wherein the composition comprises (a) a non-aqueous solvent and (b) an organic iridium complex compound dissolved in the solvent; (iii) heating the composition, and thereby forming a noble metal layer on the substrate.

Production method for noble metal electrodes

One aspect relates to a method for the manufacture of a medical electrode, including: (i) providing a substrate; (ii) applying a composition onto the substrate, wherein the composition comprises (a) a non-aqueous solvent and (b) an organic precious metal complex compound that is dissolved in the solvent; (iii) heating the composition and thereby forming a precious metal layer on the substrate, wherein the solubility of the organic precious metal complex compound in propylene glycol mono-propyl ether at 25&#xb0; C. and 1013 hPa is at least 1 mass percent, or at least 2, 3, 4, 5 or 10 mass percent, in relation to the total mass of the composition.
