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. |
