- W2945740059 abstract "Herein, we report a simple and novel approach for the design of fluorescent chemosensor through the self-assembly of functionalized monomer molecules. According to these approach, a novel supramolecular fluorescent chemosensor (SPMS) was successfully constructed by self-assembly of a quinoline hydrazone functionalized pillar[5]arene monomer PM. Interestingly, upon the addition of CN−, the solution of SPMS instantly shows dramatic fluorescent enhancement and emitting bright blue emission. Meanwhile, the fluorescence quantum yields show distinct increase from 0.0582 of SPMS to 0.3952 of SPMS + CN−. The detection limit (LOD) of SPMS for CN− is 9.70 × 10−8 M, which indicated high sensitivity. Moreover, the SPMS is selective for CN− even in the presence of other anions, the fluorescent detection process of SPMS for CN− was not interfered by other competitive anions (F−, Cl−, Br−, I−, N3−, OH−, SCN−, HSO4−, AcO−, H2PO4− and ClO4−). Notably, in the CN− sensing process, the self-assembly structure of the supramolecular chemosensor SPMS didn't show any disassembly. This work provides a novel approach for instant detection of CN− through a self-assembled supramolecular fluorescent chemosensor in aqueous system. Moreover, the test strips based on SPMS were fabricated, which could serve as convenient and efficient CN− test kits." @default.
