A new 4,5-quinolimide-based fluorescent sensor BNC was synthesized and characterized. BNC showed single selectivity for Cu2+via the “”turn-off”” fluorescence among various common metal ions. After forming a 1:1 stoichiometric complex with Cu2+, the detection limit (LOD) of BNC for Cu2+ is 0.44μM. Subsequently, the in situ generated BNC-Cu2+ complex had been used for sensing Cys with the LOD of 1.5μM through the displacement strategy, resulting in the revivable emission of BNC. According to the “”off-on-off”” fluorescence cycle of BNC generated by the alternate addition of Cu2+ and Cys, a reversible memorized device with “”read-write-read-erase”” behavior was constructed at the mol. level. Furthermore, the recoveries of Cu2+ in lake water with BNC were at 95.0-105%. And sequential fluorescence imagings of BNC for Cu2+ and Cys were successfully applied in living yeast cells.Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0Product Details of 1539-42-0) was used in this study.
Bis(pyridin-2-ylmethyl)amine(cas: 1539-42-0) is a secondary amine with two picolyl substituents. The compound is a tridentate ligand in coordination chemistry and commonly used to produce Zn-based chemosensors/probes, such as Zinpry.Product Details of 1539-42-0
