%X The polarization characteristics of electroluminescent polymers were studied with the theoretical model including the external field, electron-electron and electron-lattice interactions simultaneously. It was discovered that on-site Hubbard energy and the nearest neighbor electron-electron interactions increase the negative polarization of self-trapping bi-excitons in polymers obviously. The physical significance of negative polarization-a new phenomenon, and its possible applications were also explored.
