Arne Busing 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).

  • Electronic devices containing organic semi-conductors
    Patent number: 9150687
    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.

  • Method for the production of heteroleptic ortho-metallated organometallic compounds
    Patent number: 7745627
    Abstract: The invention relates to a method for the production of high-purity, heteroleptic, orth-etallated, organometallic compounds of application as a functional material for colouring components in a wide range of applications within the widest sense of the electronics industry. A method is thus used for the cleavage of a bridged metal dimer with organometallic substances. Dihalo complexes, which may be used as monomers for polymerisations, in particular, may be produced thus.
