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.
