Ruthenium(II) polypyridyl linked di-(2-picolyl)amine (DPA) based chemosensor [Ru(bpy)2(bpmpip)](PF6)2 (Ru-L) has been developed for the selective detection of Cu(II) ion in purely aqueous medium. The change in absorbance and emission spectra of chemosensor Ru-L was observable upon addition of Cu2+ ion. Competitive binding studies, detection limit (18.9 nM) and binding constants illustrate significant sensing ability of chemosensor Ru-L. Spectral behavior of chemosensor Ru-L at different pH was also investigated in absence and presence of Cu2+ ion. Binding of Cu2+ to Ru-L occurs in 1:1 stoichiometry, in good agreement with the results obatined from ESI-mass spectrometry, Job’s plot experiment and spectroscopic titrations The emission intensity of Ru-L was selectively quenched by Cu2+ ion and an obvious color change from red orange to yellow in aqueous solution as well as on paper strips was observed under UV light. The reversibility cycles for the detection of Cu2+ ion were achieved by EDTA and corresponding logic gate was also developed. The water solubility, reversibility and optical visualization of the present chemosensor make it ideal for practical applications on real samples.

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.Recommanded Product: 1539-42-0
