Abstract:
A new phthalimide based chemosensor 2-(Pyridin-2-yl-(pyridine-2-ylimino)methyl)isoindoline-1,3-dione (PP3) was synthesized and characterized by IR, LCMS and NMR spectroscopic methods. The metal ions sensing ability of PP3 was examined by naked-eye and UV-Vis absorption techniques. The colorless solution of PP3 turned to yellow upon addition of Cu2+ and a new absorption band appeared at 434 nm. The Job's plot and HR-MS data confirms the formation of a new complex species between PP3 and Cu2+ in 1:1 binding stoichiometry. The sensor PP3 allowed the detection of Cu2+ down to 1.65 μM without any remarkable interference from the other tested metal cations.

When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...
