| 英文摘要 | efficient solution-processed blue phosphorescent organic light-emitting diodes (oleds) featuring with halogen-free solvent processing are fabricated in this study. the organic molecule 3,6-bis(diphenylphosphoryl)-9-(4 '-(diphenylphosphoryl) phenyl)-carbazole (tpcz) that possesses good solubility in halogen-free polar solvents is selected to serve as the host of blue phosphorescent iridium(iii) [bis(4,6-difluorophenyl)-pyridinato-n,c-2]-picolinate (firpic) dopant. the morphology of the tpcz: firpic emissive layer prepared with different polar solvents including chlorobenzene (cb), n-butanol (buta) and isopropanol (ipa) and the effect on their electroluminescent performance have been investigated in detail. it is found that the more polar halogen-free solvent ipa restrains the firpic aggregation and renders a more densely packed emissive layer as compared to the cb-processed counterpart, which results in the enhanced electroluminescent performance. the luminous efficiency and power efficiency of the blue phosphorescent oleds prepared with cb are merely 5.7 cd/a and 3.3 lm/w, respectively. when using more polar halogen-free solvent ipa, the efficiencies are enhanced to 22.3 cd/a and 15.6 lm/w, about 2.9 and 3.7-time increment, respectively. this work provides an approach to fabricate efficient solution-processed phosphorescent oleds with environmental-friendly solvents, which is highly required in large-scale solution-processed manufacturing.
