A process for the production of organic field effect transistors and based thereon circuits on solvent and temperature-sensitive plastic surfaces and organic field effect transistors and organic optoelectronic devices according to this method

The invention relates to the production of organic field effect transistors (OFETs), solar cells or light-emitting diodes (OLEDs), and based thereon circuits on the surface of solvents and / or temperature-sensitive plastics, z. B. thermoplastic injection moldings. A protective layer consisting of a polymer compound such as polyacrylate, polyphenol, melamine resin or polyester resin, which is less of an aqueous-alcoholic solution or without solvent to the substrate surface or one of the function-determining layers of the electronic HL-component in a low temperature process at temperatures over 100 ° C is applied and dried, protects the substrate from undesirable action of a solvent and can also serve as a planarization layer and / or as eketrische insulating layer.
