摘要：采用Wittig方法制得了未封端及封端的线性聚三苯胺-对苯乙烯撑型聚合物(分别简称为:TPA-DOPPV1,TPA-DOPPV2),并对共轭聚合物进行了表征和性能测试。封端后的聚合物溶液和固体膜在紫外光照射下均发出较强的绿光。对这类聚合物在硝基化合物检测方面的应用进行了初步研究,结果表明:封端后的共轭聚合物在邻硝基甲苯(o-NT)荧光检测上的性能明显提高,当o-NT浓度为21.5×10-3mol/L时,荧光猝灭效果达到了96%;在2,4-二硝基甲苯(DNT)、对硝基甲苯(p-NT)和对苯醌(p-BQ)蒸汽中放置10 s时,其薄膜的荧光猝灭效率分别达到30%、15.6%和3.1%。TPA-DOPPV2的合成操作较为简便,具有一定的检测灵敏性,是一种潜在的硝基类爆炸物荧光检测材料。
The non-terminated and terminated linear polymers poly（triphenylamine-p-phenylenevinylenes） were prepared through a wittig polycondensation. Structures of two copolymers were characterized. UV and PL spectra show the terminated polymer emits intensive green light in solution and film state. Applications in the detection of nitro compound were studied, and results showed high fluorescence quenching sensitivity of the terminated polymer towards o-NT. When the concentration of o-NT is 21.5 10^-3 mol/L, fluorescence quenching reaches 96% . Additionally, after the exposure of polymer film in three different quenchers such as DNT, p-NT and p-BQ for 10 s, fluorescence quenching reaches 30%, 15.6 % and 3.1% respectively. This kind of polymer exhibits great advantages in preparation and detection, indicating the potential application value in the detection of nitro explosive.
