Patents by Inventor Amir Parham

Amir Parham 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).

  • 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).
    Type: Grant
    Filed: March 22, 2002
    Date of Patent: October 30, 2007
    Assignee: Merck Patent GmbH
    Inventors: Kevin Treacher, Heinrich Becker, Philipp Stossel, Hubert Spreitzer, Aurelie Falcou, Amir Parham, Arne Busing
  • Publication number: 20070123690
    Abstract: The present invention relates to conjugated polymers which comprise coumarin structural units or related units of the formula (1). The materials according to the invention exhibit significantly higher photostability than materials in accordance with the prior art and are therefore more suitable for use in polymeric organic light-emitting diodes.

    Inventors: Philipp Stössel, Amir Parham, Horst Vestweber, Hubert Spreitzer
  • Publication number: 20070034862
    Abstract: The present invention describes a novel design principle for organic electronic elements by inserting at least one additional crosslinkable layer. The properties of the electronic devices are thereby improved. Structured construction of these devices is furthermore facilitated.

  • Publication number: 20060284140
    Abstract: The present invention relates to mixtures and to conjugated polymers which contain bridged carbazole structural units and structural units which emit light from the triplet state. The inventive mixtures exhibit improved efficiencies and reduced operating voltages and are therefore better suited to use in organic light-emitting diodes than comparative materials which do not comprise these units.

  • Publication number: 20060149022
    Abstract: The present invention relates to conjugated polymers comprising specific carbazole structural units. The materials according to the invention display steeper current-voltage curves and are therefore better suited to use in organic light-emitting diodes than are comparative polymers which do not contain these units.

  • Publication number: 20060052612
    Abstract: The invention relates to novel compounds containing 2,1,3-benzothiadiazole. Said compounds can be used as active components (=functional materials) in a series of different applications that can be attributed in the broadest sense to the electronics industry. The inventive compounds are defined by the formulae (I), (II), (III), (IV), (V), (VI), (VI), (VIII), (IX), (X) and (XI).
