  • Polymers and compounds based on dipyrrolo[1,2-B:1',2'-G][2,6]naphthyridine-5,11-dione
    Patent number: 10442888
    Abstract: Polymers containing a repeating unit of the formula —[Ar—Y—Ar?]— (V), and compounds of formula R10—Ar—Y—Ar?—R10? (I), where Y is a group of formula and organic devices containing the polymers. The polymers and compounds have excellent solubility in organic solvents and excellent film-forming properties. In addition, high efficiency of energy conversion, excellent field-effect mobility, good on/off current ratios and/or excellent stability can be observed, when the polymers and compounds are used in organic field effect transistors, organic photovoltaics and photodiodes.
    Type: Grant
    Filed: October 20, 2016
    Date of Patent: October 15, 2019
    Assignee: BASF SE
    Inventors: Marek Grzybowski, Daniel T. Gryko, Bartlomiej Sadowski, Karen Strassel, Pascal Hayoz, Daniel Kaelblein
