Synthesis and Properties of Electrophosphorescent Conjugated Polymers Containing Iridium Complexes in Polymer Backbone

摘要

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 PFOPPylr were investigated. A luminance efficiency of 3.80 cd/A and luminance of 1248 cd/m~2 were achieved.
