  • Bay-annulated indigo (BAI) as an excellent electron accepting building block for high performance organic semiconductors
    Patent number: 9315671
    Abstract: A novel electron acceptor based on bay-annulated indigo (BAI) was synthesized and used for the preparation of a series of high performance donor-acceptor small molecules and polymers. The resulting materials possess low-lying LUMO energy level and small HOMO-LUMO gaps, while their films exhibited high crystallinity upon thermal treatment, commensurate with high field effect mobilities and ambipolar transfer characteristics.
    Type: Grant
    Filed: November 16, 2015
    Date of Patent: April 19, 2016
    Assignee: The Regents of the University of California
    Inventors: Yi Liu, Bo He, Andrew Pun
