Patents by Inventor Roland Haasmann

Roland Haasmann 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).

  • Method of producing organic semiconductors having high charge carrier mobility through &pgr;-conjugated crosslinking groups
    Patent number: 6828406
    Abstract: The organic polymers of the invention have electrical semiconductor properties. The compounds have a backbone of phenylene groups to which side groups with semiconductor properties, or which impart semiconductor properties to the polymer, are bonded. The polymers are obtained by Bergmann cyclization from compounds that contain aromatic groups to which vicinal ethynyl groups are bonded. The polymers are suitable for the production of semiconductor components, such as organic transistors or diodes.
    Type: Grant
