通过Heck反应合成了PFO/PPV共聚物，采用FT-IR、1H NMR、TGA等对共聚物结构进行了表征，其重均分子量为4 400，分子量分布为1.2。共聚物具有良好的热稳定性，在室温到700 ℃范围内只有一次明显的失重，初始分解温度为280 ℃，在350～450 ℃之间失重约50%。EHOMO/ELUMO、Eg分别为－6.09/－3.20、2.89 eV。利用UV-Vis和PL研究了共聚物的光学性能，结果表明，共聚物具有较强的荧光性，其荧光最大发射峰位于490 nm波长处。将制备的共聚物薄膜作为发光层，引入纳米ZnO作为功能层，在柔性PET衬底上制作的PLED器件的启动电压为4.2 eV，发蓝光。

The copolymer of polyfluorene/poly(p-Phenylene vinylenes) (PFO/PPV) was synthesized through Heck reaction. The structure of the obtained copolymer was characterized by FT-IR, 1H NMR, TGA, etc. The molecular weight and poly dispersity of the copolymer were 4 400 and 1.2, respectively. The copolymer had good thermal stability,it had only one weightlessness from RT to 700 ℃ and the weightlessness was about 50% at 350～450 ℃. EHOMO/ELUMO and Eg was－6.09/－3.20 and 2.89 eV respectively. The optical properties, revealed by UV-Vis and PL, showed that copolymer had excellent luminescence, with a maximum peak of fluorescence emission at 490 nm. The copolymer was also tested as an emitting layer for flexible polymer light-emitting diode (PLED) device, where nano ZnO as a functional layer, showing a turn-on voltage of about 4.2 V and emitting blue electroluminescence.
