合成了含不同含氟苯(氟苯、对二氟苯和四氟苯)基团的荧基聚合物。此外，还对poly-[(9，9-dioctylfluorene-2，7-diyl)-co-(fluorene-2，7-diyl)]进行了全氟辛基化反应，合成了含全氟辛基的荧环上9位聚合物。为了评价含氟量的影响，合成了含非氟苯基团和非氟辛基的聚合物。光致发光测试表明，所有聚合物在溶液中都有蓝光发射，但含有全氟辛基的聚合物在薄膜状态下没有蓝光发射。含不同含氟苯基团的聚合物比含非氟苯基的聚合物具有更高的荧光量子产率和热稳定性。©2001 John Wiley&Sons，Inc.J Polym Sci Part A：Polym Chem 39：3143-3150,2001
Fluorene-based polymers containing various fluorinated benzene (fluorobenzene, p-difluorobenzene, and tetrafluorobenzene) moieties were synthesized. In addition, perfluorooctylation of poly-[(9,9-dioctylfluorene-2,7-diyl)-co-(fluorene-2,7-diyl)] was carried out to afford fluorene-based polymers with perfluorooctyl moiety at the 9-position on the fluorene ring. To evaluate the effect of fluorine moiety, polymers containing nonfluorinated benzene moieties and nonfluorinated octyl groups were synthesized. The photoluminescence measurements indicated that all these polymers exhibited blue emission in solution, but a polymer containing a perfluorooctyl group did not emit in the film state. Polymers containing various fluorinated benzene moieties showed higher fluorescence quantum yields and thermal stability than those containing nonfluorinated benzene. © 2001 John Wiley & Sons, Inc.
