Tetrahedron Letters, 54(21), 2633-2636. | Series/Report no.: | Tetrahedron letters | Abstract: | A novel heteroacene, 2-(2,3,4,5-tetrafluorophenyl)-1H-imidazo[4,5-b]phenazine has been successfully synthesized. The heteroacene can selectively detect F− over Cl−, Br−, I−, NO3−, HSO4−, ClO4−, and BF4− in organic solvents through colorimetric and fluorescent responses. The interaction between the heteroacene and F− was investigated through UV–Vis, fluorescence, and 1H NMR titration experiments, which suggested that the effects might occur via a combined process including hydrogen bond, deprotonation, and anion–π interactions between the sensor and F−. | URI: | https://hdl.handle.net/10356/106261 http://hdl.handle.net/10220/17868 |
