  • Conjugated polymer and semiconductor devices including the same
    Patent number: 9023964
    Abstract: The present invention relates to conjugated polymers. In various embodiments, the present invention provides a conjugated polymer including a repeating unit including a benzene ring conjugated with the polymer backbone, wherein the benzene ring is fused to two 5-membered rings, wherein each fused 5-membered ring includes N and at least one of O and S. In various embodiments, the present invention provides semiconductor devices including the polymer, and methods of making the polymer.
    Type: Grant
    Filed: March 12, 2014
    Date of Patent: May 5, 2015
    Assignee: Iowa State University Research Foundation, Inc.
    Inventors: Malika Jeffries-EL, Jeremy J. Intermann, Brian C. Tlach

  • Monocapped conductive polymers with alkenyl or alkynyl end groups and block copolymers therefrom
    Patent number: 8754175
    Abstract: Novel polymer compositions which provide controlled end-group functionalization for polythiophenes including regioregular polythiophenes including alkenyl and alkynyl functionalization. Monocapped polymers are formed and can be converted to block copolymers. Conditions and reagents can be selected to provide more monocapping than dicapping of the polymer. Devices, films, and blends can be prepared.
