Synthesis and properties of electrophosphorescent conjugated polymers containing iridium complexes in polymer backbone
A novel series of electrophosphorescent conjugated poly-fluorenes (PFOPPyIr) based on (4,4'-dibromophenylpyridinato-N,C-2)bis(2-phenylpyridinato-N,C-2)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/m(2) were achieved.
