Electrophosphorescent polymers are an important class of light-emitting materials that combine high electroluminescence efficiency of organometallic phosphohrescent complexes and solution processability of polymers. This review surveys the progress in the design, synthesis, characterization, photoluminescence and electroluminescence of electrophosphorescent polymers reported in the recent literatures. It focuses on polymers with phosphorescent guest covalent bonded to the polymers as a repeating unit in the main chain, a side chain, or polymer chain termini. The polymer backbones either have an extended π-electron conjugation or are non-conjugated. Important electrophosphorescent polymers and their performance in light emitting diodes are described.
Keywords: Electrophosphorescence, organometallic polymer, energy transfer, polymer light-emitting diodes
