摘要：本实验采用Wittig方法制得了未封端和封端的超支化聚三苯胺-对苯乙烯撑型聚合物,对两种共轭聚合物进行了表征和性能测试.聚合物溶液和固体膜在紫外光照射下均发出较强的绿光.首次对这类聚合物在硝基芳烃化合物荧光猝灭能力进行了初步研究,结果表明:与未封端产物相比,封端后的超支化共轭聚合物在邻硝基甲苯(o-NT)的荧光猝灭效率上有明显提高,当o-NT浓度为21.5×10-3mol/L时,荧光猝灭效率达到97%.这类共轭聚合物不仅合成操作较为简便,猝灭效率也较高,是一种很有潜力的硝基芳烃化合物荧光检测材料.
The non-capped and capped hyperbranched conjugated polymers Poly （triphenylamine-p- Phenylenevinylenes） were obtained through a Wittig polycondensation. The structures of two copolymers were characterized. UV and PL spectra showed two hyperbranched conjugated polymers emited intensive green light in solution and film state. It is the first time to research their application in the fluorescence quenching ability of nitro compound, and the results showed high fluorescence quenching efficiency of the capped polymer towards o-NT, compared to non-capped product. When the concentration of o-NT was 21.5 × 10^-3 mol/L, its fluorescence quenching reached 97%. This kind of polymer exhibited great advantages in quenching efficiency and preparation, indicating the potential application value in the detection of nitro compounds.
