In this study, NBA imine compound was synthesized via an easy one-pot condensation of 3-nitro-benzaldyhide with 2-amino benzoic acid in 1:1 ratio and DAPH imine compound derived from 2,6-diacetyl pyridine and phenyl hydrazine hydrochloride. Consequences of the newly synthesized compounds hooked up with the aid of FT-IR, elemental analyses, 13C-NMR ,1H-NMR and digital spectral research. Experiments had been consistent with their chemical structures. Theoretical DFT calculations had been implemented to confirm the molecular geometry of the investigated chemo-sensors. The sensor property of all organized imines had been tested upon addition of the metal ions, consisting of Cr(III) , Fe(II) , Co(II) , Ni(II) , Cu(II) , Zn(II) , Mn(II), VO(II) and Pd(II) . The interactions among receptors and ions are effortlessly monitored with the aid of UV-visible spectroscopy. DAPH receptor confirmed color modification from blood red to excessive deep green color to Co(II) , a yellow color to Cu(II) and different colors to different ions. Where the NBA receptor showed color modification from light yellow to excessive deep orange color to Fe(II), pale orange to Pd(II) and different colors for other ions.
