| 摘 要： | 以3, 6-二溴-9-辛基咔唑和2, 5-二戊烷氧基-1, 4-二乙炔基苯为单体,通过Pd催化的Sonogashira偶联反应合成了聚对苯撑乙炔咔唑衍生物PPECz。PPECz的溶液和固体薄膜都具有较好的发光性能,并且均对2, 4, 6-三硝基甲苯(TNT)有明显的响应。在常温常压条件下,微量(40 μg)的TNT挥发物在60 s内就能使聚合物PPECz薄膜的荧光强度被猝灭56%,可作为一种潜在的硝基苯类爆炸物的荧光检测材料。

| Abstract: | Poly(phenylene ethynylene) containing carbazole unit in the main-chain (PPECz) was synthesized by Pd-catalyzed Sonogashira coupling reaction between 3,6-dibromo-9-octylcarbazole and 2,5-dimethoxy-1,4-diethynylbenzene. PPECz in the solution and thin film exhibits obvious luminescence properties, which can be used to detect TNT sensitively. The fluorescence intensity of PPECz thin-film can be quenched 56% by the volatile of 40 μg TNT solid at 60 s at normal atmospheric temperature and pressure. This strategy can provide a platform for developing highly sensitive and efficient chemo sensors for warfare explosives. |
