ABSTRACT:
The present invention is related to electroluminescent polymer materials for use in optoelectronic devices. The electroluminescent polymer materials of the invention may comprise a polymer and an electroluminescent organic component, where the water-soluble polyanilin having an electron-hole conductivity may be used as the polymer and one of a cyanine dye, a porphyrin, in the form of J-aggregates, may be used as the electroluminescent organic component.
