A fluorescent ratiometric nanosized system for the determination of Pd(II) in water

A fluorescent ratiometric nanosized system for the determination of Pd(II) in water

The fluorescent ligand (L) based on the N2S2 pyridinophane macrocycle and the 7-nitrobenzo[1,2,5]oxadiazole (NBD) fluorogenic fragment has been synthesized to coordinate Pd(II) ions. Loaded on dye-doped silica nanoparticles, L can be used as a ratiometric fluorescent chemosensor for Pd(II) in water...

Zusammenfassung:The fluorescent ligand (L) based on the N2S2 pyridinophane macrocycle and the 7-nitrobenzo[1,2,5]oxadiazole (NBD) fluorogenic fragment has been synthesized to coordinate Pd(II) ions. Loaded on dye-doped silica nanoparticles, L can be used as a ratiometric fluorescent chemosensor for Pd(II) in water with high selectivity toward other metal ions including the platinum group ones.
