  • Molecular compositions, materials, and methods for efficient multiple exciton generation
    Patent number: 10636974
    Abstract: Embodiments of the present invention provides compounds, compositions, and methods for their preparation that provide efficient intramolecular fission, such that local order and strong nearest neighbor coupling is no longer a design constraint. Inventive materials include organic oligomers and polymers designed to exhibit strong intrachain donor-acceptor interactions and provide intramolecular singlet fission, whereby triplet populations can be generated in very high yields of, e.g., 170% or more.
    Type: Grant
    Filed: October 24, 2016
    Date of Patent: April 28, 2020
    Assignees: THE TRUSTEES OF COLUMBIA UNIVERSITY IN THE CITY OF NEW YORK, BROOKHAVEN SCIENCE ASSOCIATES, LLC.
    Inventors: Luis Miguel Campos, Matthew Y. Sfeir, Jianlong Xia, Erik Michael Allan Busby, Jonathan Zhaozhi Low

  • [N]cycloparaphenylenes (CCP), [N]macrocycle intermediates and methods of making same
    Patent number: 9090473
    Abstract: The present invention provides the compound [6]-cycloparaphenylene, cycloparaphenylene intermediates (e.g. [n]macrocycles), and methods for making [n]cycloparaphenylenes and [n]cycloparaphenylene intermediates in quantities not previously available. The cycloparaphenylene compounds and their intermediates can be useful in nanotube preparation and in the preparation of other supramolecular structures.
