Abstract

A dual nature Schiff base chemosensor“3,5-bis(((2-hydroxynaphthalen-1-yl)methylene)amino) benzoic acid” (3,5-BHNMABA) was synthesized and characterized by single crystal X-rays diffraction. The interaction of the photophysical properties of the ligand with various metal ions (aqueous) was extensively analyzed through fluorescence spectrophotometry. E_HOMO-E_LUMO energy gap and molecular electrostatic potential study was performed by DFT calculations. Strong quenching in emission was observed for Cu²⁺ and Ce⁴⁺ ions. Binding ratio between Cu²⁺/Ce⁴⁺ ions with ligand was calculated by Job’s plot. LOD and LOQ were calculated as 7.92 × 10^-6 M and 2.40 × 10^-5 M for Cu²⁺ ions whereas 5.9 × 10^-6 M and 1.97 × 10^-5 M for Ce⁴⁺ ions.

期刊介绍： Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
