In this study, 1H-pyrazole- azomethine based novel diazo derivative disperse azo dye was synthesized by a simple one-pot condensation reaction of 5-amino-3-methyl-4-phenylazo-IH-pyrazole (2) and salicylaldehyde in 1:1 ratio. This newly synthesized dye was characterized by elemental analysis and spectral techniques. The sensor properties of the SAG-1 was examined upon addition of the metal ions, such as Na+, K+, Mg2+, Ca2+, Sr2+, Al3+, Cr3+, Mn2+, Cd2+, Co2+, Fe2+, Fe3+, Ni2+, Cu2+, Zn2+, Hg2+ and Pb2+. The interactions between receptor and ions were monitored by UV-Vis method. In addition, SAG-1-Ni2+ complex was investigated by UV-Vis spectroscopy with the detection of stoichiometry and binding constants of the complex. (C) 2020 Elsevier B.V. All rights reserved.
