  • Process of preparing regioregular polymers
    Patent number: 8221652
    Abstract: The invention relates to a process of preparing regioregular polymers, in particular head-to-tail (HT) poly-(3-substituted) thiophenes or selenophenes with high regioregularity and defined molecular weight, to novel polymers prepared by this process, to the use of the novel polymers as semiconductors or charge transport materials in optical, electrooptical or electronic devices including field effect transistors (FETs), electroluminescent, photovoltaic and sensor devices, and to FETs and other semiconducting components or materials comprising the novel polymers.
    Type: Grant
    Filed: December 10, 2007
    Date of Patent: July 17, 2012
    Assignee: Merck Patent GmbH
    Inventors: Timo Hoffart, Birgit Falk, Iain McCulloch, Weimin Zhang, Martin Heeney
