In this paper, we report a new pyrene imine derivative which bears a relatively rigid intramolecular hydrogen bonding pocket, for fluorescent and colorimetric sensing of cyanide. In CH3CN solution, the chemosensor displayed distinct fluorescent and UV absorption changes towards CN−, CH3CO2−, F−, and H2PO4−. Notably, in an aqueous CH3CN medium (10%, v/v), the selectivity towards cyanide over other various
在本文中,我们报告了一种新型的im亚胺衍生物,该衍生物带有一个相对较硬的分子内氢键口袋,用于氰化物的荧光和比色传感。在CH 3 CN溶液中,化学传感器显示不同的荧光和UV吸收的变化朝向CN - ,CH3CØ2-,F -和H2PØ4-。值得注意的是,在CH 3 CN水性介质(10%,v / v)中,观察到对氰化物的选择性高于其他各种阴离子,并具有明显的荧光增强和比色变化。因此,我们证明了via基化学传感器对阴离子的选择性可以通过控制不同溶剂体系中的氢键相互作用来优化。最后,通过活HeLa细胞证明了化学传感器在荧光成像细胞氰化物变化中的应用。
