摘要：

The fluorescent-conjugated microporous polymer-based carbazole derivatives (DCZP and DCZN) have been successfully synthesized by palladium-catalyzed Sonogashira-Hagihara cross-coupling of 1,3,6,8-tetrabromo-9H-carbazole and 1,4-diethynylbenzene monomers using both solution polymerization and miniemulsion polymerization. The resultant DCZP and DCZN are provided with a large BET surface area of over 688 and 97 m(2) g(-1) with a pore volume of 0.43 and 0.15 cm(3) g(-1), and the pore distributions are concentrated at around 1.65, 3.82 and 1.99, 2.33 nm. The polymers, especially DCZN, display strong fluorescent emission by excitation at 365 nm in THF suspension and exhibit a high sensitive to picronitric acid, indicating that the three-dimensional pi-conjugated polymer frameworks combined with permanent microporous and fluorescent properties make these polymers utilized as sensors for nitroaromatics detection.
