TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The solution contains: a polar solvent, by which the organic material is dissolved, and/or an electrically conductive additive; a non-polar solvent, by which the organic material is dissolved; and a volatile polar solvent, which is an alcohol, preferably ethanol or methanol, or acetonitrile. The solvent is: toluene, chlorobenzene, dichlorobenzene, xylene, chloroform or tetrahydrofuran; or ethanol, methanol, isopropanol, chloroform or dichloromethane. The additive is acids or salts e.g. formic acid and acetic acid. The organic material is low-molecular, polymeric or oligomeric crosslinkable hole conductor materials on the basis of triarylamine with oxetane as reactive group or other oxetane crosslinkable hole conductor materials. The solution and the surface, on which the buffer layer is applied, exhibit an electrical potential difference. The solution contains non-fluorinated, partially-fluorinated and perfluorinated additives comprising 3-ethyl-3-(6-(3-ethyloxetan-3-yl)hexyl)oxetane, 3-ethyl-3-(2-(2-(2-(2-(2-(3-ethyloxetan-3-yl)ethoxy)ethoxy)ethoxy)ethoxy)ethyl)oxetane and bis((3-ethyloxetan-3-yl)methyl)octanedioate. Preferred Process: The spraying solution is sprayed with the help of an electrical field. In the process, hole conductor materials or electron conductor materials are separated by spraying process. In the process, emitter materials, photovoltaic active materials, material mixtures, electron acceptor materials such as fullerene derivative or electron donor materials such as thiophene derivative or other nitrogen- or sulfur-heterocycles, materials with low refractive index are sprayed, where the emitter materials are singlet emitters, triplet emitters, low-molecular emitters, oligomeric emitters and polymeric emitter materials. In the process, a 10-1500 nm thick buffer layer is applied by spraying as a component of an electronic device. The solution with the organic material present in it is sprayed over a capillary or a nozzle, and the distance between the capillary and/or nozzle and the surface, which is to be coated, of the electronic device changes during the layered structure. The sprayed solution is changed in the process of the layered structure, where layers of different materials and/or different refractive indices are separated (potential gradient). The materials are separated by spraying and subsequently by crosslinking. The solution with the organic material present in it is applied as buffer layer, so that injection barriers for charge carriers are lowered.
