A pyrene-cored conjugated microporous polycarbazole for sensitive and selective detection of hazardous explosives

Abstract In this article, we report the synthesis and characterization of a highly luminescent conjugated microporous polycarbazole (CK-CMP) by FeCl 3 -induced oxidative polymerization of 1,3,6,8-tetrakis(4-(9H-carbazol-9-yl)phenyl)pyrene (L). The CK-CMP with small pore sizes exhibits good thermal stability and high luminescence when suspended in polar solvents upon irradiation by UV light, which can be applied to detect 2,4,6-trinitrophenol (PA) with good sensitivity and selectivity by fluorescence quenching.
