| 摘 要： | 通过Heck缩聚反应合成支化型聚芴/聚对苯乙烯撑(PFO/PPV)共轭齐聚物并且与介孔二氧化硅MCM-41复合成主-客体材料.使用紫外吸收光谱、荧光光谱手段表征了介孔复合薄膜的光化学性能.研究了该复合膜对硝基芳香烃物质的荧光猝灭性能.实验结果表明该介孔复合物比一般的共轭高分子检测灵敏度更高,使用期限更长,在硝基芳香烃爆炸性物质的检测上有着潜在的应用价值.

| Abstract: | A branched conjugated oligomer of Polyfluorene/Poly(p-Phenylene vinylenes)(PFO/PPV) was synthesized through Heck condensation approach and incorporated into mesoporous silica of MCM-41.The photophysical properties of the mesoporous composite film were studied by UV and PL spectroscopy.The fluorescence quenching properties of the composite film was investigated.The results indicate that the composite film,due to the higher fluorescence quenching sensitivity and longer lifetime than the many other conjugated ... |
