  • White electroluminescent polymeric material and preparation thereof
    Patent number: 7579091
    Abstract: This invention relates to a white electroluminescent polymeric material and preparation thereof. Based on the physical idea that white light emission can be achieved by regulating the relative luminous intensities of blue- and orange-light emitting units located in a single polymer molecule, the present invention provides three types (main chain type, pendant chain type, and terminal group type) of high efficiency and stable white electroluminescent polymeric material systems.
    Type: Grant
    Filed: January 26, 2005
    Date of Patent: August 25, 2009
    Assignee: Changchun Institute of Applied Chemistry Chinese Academy of Science
    Inventors: Lixiang Wang, Guoli Tu, Jianxin Cao, Jun Liu, Dongge Ma, Xia Bin Jing, Fosong Wang
