A novel series of electrophosphorescent conjugated polyfluorenes (PFOPPyIr) based on (4,4′-dibromophenylpyridinato-N,C2)bis(2-phenylpyridinato-N,C2)iridium(III) were synthesized, in which the polymer main chains consist phenylpyrridine ligand and fluorene segment with extended conjugation. The optical and electroluminescent properties of PFOPPyIr were investigated. A luminance efficiency of 3.80 cd/A and luminance of 1248 cd/m2 were achieved.
