摘要
通过Heck缩聚反应首次合成了线型聚芴／聚对苯乙烯撑（PFO／PPV）共轭聚合物，通过FT-IR、^1H-NMR、GPC和TGA等测试表征了聚合物的结构。该聚合物具有良好的溶解性和热稳定性。紫外吸收光谱、荧光分光光度计等手段表征了聚合物的光学性质及其稀溶液的荧光淬灭性质，结果表明该聚合物的二氯甲烷溶液对4-硝基甲苯具有良好的淬灭敏感性。作为新型荧光传感材料，该聚合物在含硝基芳香烃爆炸性气体的检测上有着潜在的应用价值。
The conjugated polymer of polyfluorene/poly（p-Phenylene vinylenes） （PFO/PPV） which was synthesized through heck condensation coupling. The structure of the obtained polymer was characterized by FT-IR, ^1H-NMR, GPC. The polymer has good solubility. The optical and fluorescence quenching properties in dilute solution of the polymer is revealed by UV-Vis, PL Spectroscopy. It shows PL quenching sensitivity towards 4-nitrotoluene in CH2Cl2. It indicates that the polymer has the potential to be used as fluorescence sensing material for chemical vapour.
