The interaction of the photophysical properties of the ligand with various metal ions (aqueous) was extensively analyzed through fluorescence spectrophotometry. EHOMO-ELUMO 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 x 10-6 M and 2.40 x 10-5 M for Cu2+ ions whereas 5.9 x 10-6 M and 1.97 x 10-5 M for Ce4+ ions.eninfo:eu-repo/semantics/closedAccessSchiff baseX-ray crystal structuresTurn-off fluorescentJob's plotCu 2+ionsCe 4+ionsArticle17210.1016/j.inoche.2024.1136662-s2.0-85211044565Q2WOS:001375016300001Q1
