Abstract

By simply doping Li₂CO₃ in an alcohol soluble neutral conjugated polymer poly[9,9-bis(6′-diethoxylphosphorylhexyl)fluorene] (PF-EP), we demonstrate highly efficient multilayer electrophosphorescence white polymer light-emitting diodes with air-stable Al cathode. From the mechanism studies, we find that the phosphate groups can make Li ions movable in the PF-EP film, resulting in great improvement in the electron injection and transport ability of PF-EP. The hole-blocking ability is also strengthened.
