Electrophosphorescent materials and their excellent properties have attracted significant attention because of their potential application as highly efficient electroluminescent emitters in organic light emitting diodes （OLEDs）. Iridium （III） complexes were selected as optimal materials for electrophosphorescent material synthesis as their strong spin orbit coupling may result in high luminescence efficiencies, a short excited-state lifetime and excellent color change from blue to the near-infrared region. Polymer iridium complex electrophosphorescent materials combine the processing properties of polymers and the optical properties of the small molecule iridium （III） complexes and were used with ease in the fabrication of large-scale structures in OLEDs by spin-coating. Several important syntheses methods of these polymer metal complexes are reviewed in this article. Furthermore, the merits and demerits of these methods are also discussed. Finally, synthesis problems were highlighted and some perspectives were proposed for future study.
