  • Electroluminescence in light emitting polymers featuring deaggregated polymers
    Patent number: 6962757
    Abstract: In general terms, the present invention includes a light emitting polymeric material the light emitting polymeric material capable of producing electroluminescence upon being provided with a flow of electrons, the light emitting polymeric material comprising a plurality of polymeric chains comprising polymeric chains each having substituent moieties of sufficient number and size and extending from the polymeric chain and about a substantial portion of the circumference about the polymer chain so as to maintain the polymeric chains in a sufficiently deaggregated state (referred to herein as a “strapped” polymer), so as to substantially prevent the redshifting of the electroluminescence and the lowering of light emission efficiency of the electroluminescence.
    Type: Grant
    Filed: August 27, 2003
    Date of Patent: November 8, 2005
    Assignee: The Ohio State Universtiy Research Foundation
    Inventors: Arthur J. Epstein, Yunzhang Wang, Darren D. Gebler, Timothy M. Swager
