| 英文摘要 | Starting from 2, 7-dibromofluorene, two aryl substituents were introduced to the 9-position of fluorene to replace the commonly used alkyl groups so as to increase the stability of fluorene. New hyperbranched polymers that exhibited excellent thermal and luminescent stability were synthesized using newly designed monomers through the "AB(2) + AB" approach. The decomposition temperatures of all hyperbranched polymers are above 400 degrees C. The polymer films heated at 200 degrees C in air for 2 h were not observed green emission band. Compared with alkyl substituted polyfluorenes, the luminescence stability has a marked improvement. DSC results show that linear polymers have a glass transition at 170 degrees C, but hyperbranched polymers do not have an obvious phase transition under 300 degrees C, indicating hyperbranched polyfluorenes form amorphous films, which help to improve the efficiency of PLEDs. |
