A Novel Water Soluble Bipyrazolic Tripod Azoic Dye as Chemosensor for Copper (II) in Aqueous Solution

A novel copper (II) chemosensor based on water soluble azoic dye with bipyrazolic tripod moiety has been synthesized. The spectroscopic data’s of the presented chemosensor and its complex formation with several metal ions are studied in water via colorimetric titrations. The obtained results show that the developed chemosensor presents a high selectivity towards copper (II) in the presence of other metal ions in the typical pH range of biological systems with a detection limit of 0.84 μM.
