Hubert Spreitzer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20080113468
    Abstract: The present invention relates to electronic devices comprising organic semiconductors whose content of halogens is less than 20 ppm. This increases the lifetime and the efficiency of the corresponding electronic devices, and these materials are thus better suited to use in organic electronic devices than materials with a higher halogen content. The present invention further relates to corresponding organic semiconductors and to a process for their production.

  • Patent number: 7288617
    Abstract: The present invention relates to novel polymers which comprise spirobifluorene and fluorine units of the formulae (I) and (II) and may further comprise additional structural elements which may have charge transport properties, hole transport properties and/or electron transport properties. Such materials display a significantly improved property profile in electronic components, particularly when used in a PLED, in particular as electroluminescence material, in organic integrated circuits (O-ICs), organic field effect transistors (OFETs), organic thin film transistors (OTFTs), organic solar cells (O-SCs) or organic laser diodes (O lasers).

  • Patent number: 7250519
    Abstract: The invention relates to a method for the production of tertiary amines by reaction of secondary amines with aromatics or heteroaromatics in the presence of a base, a nickel or palladium compound and one or several phosphines, dialkoxy-, and/or diaryloxyphosphines in an inert solvent. Aromatic or heteroaromatics of this type play an important role in industry as reagents or intermediates for pharmaceuticals and agrochemicals and in diverse fine and electronics chemicals, above all in the rapidly growing field of organic semi-conductors, in particular in organic or polymeric light diodes, organic solar cells and organic ICs.

  • Publication number: 20070173578
    Abstract: The invention relates to solutions of at least one organic semiconductor containing at least one high-molecular constituent, in a solvent mixture of at least three different organic solvents A, B and C. The invention is characterised in that the solvents A and B are good solvents for the organic semiconductor, the solvent C is a bad solvent for the organic semiconductor, and Sdp.(A)<Sdp.(C)<Sdp.(B) holds good for the boiling points (Sdp.) of the solvents. The invention also relates to the use of said solutions in printing methods for producing layers of the organic semiconductor on substrates, especially in the electronics industry.
