| 中文摘要 | the morphology of fluorescent polyfluorene (pf) derivatives has strong effects on their electroluminescent (el) performance. herein, the influence of processing solvents on the morphology of pf-based white emissive polymer and its correlation to the el behavior is studied. it is found that the pf copolymer films prepared from chlorobenzene:toluene (cb:tol) solvent mixtures show stronger tendency to form crystalline alpha phase pf upon thermal annealing than those prepared from pure tol or cb solvents. the evaporation rate difference in solvent mixtures can assist in the formation of crystal nucleus and enhance the crystallinity of pf backbone after thermal annealing. the results also reveal that the solvent mixture-processed fluorescent pf-based white emissive polymer not only shows more efficient blue emission, but also more balanced electron and hole transport. accordingly, both the white emission purity and the light-emitting efficiency of the light-emitting diodes based on pf-based white emissive polymer are greatly enhanced.
