This study reports on the selective sensing of fluoride ion using a specific ligand and its metal complexes, and investigates the morphology and anion-sensing properties of the compounds using microscopic and spectroscopic techniques. H-1 NMR titration and quantum chemical calculations were conducted to understand the interaction between the chemosensors and fluoride ions, providing insights into the mechanism of their interaction.
Herein we report the selective sensing of fluoride ion with kalanchoe flower-like ligand, L (2-chloro-3-((3-dimethylamino)propylamino)naphthalene-1,4-dione) and it's metal (K1-Cu(II), K2-Co(II), K3-Zn(II)) complexes. The morphology and anion sensing properties of the L and K1-K3 compounds were investigated with microscopic and spectroscopic techniques. H-1 NMR titration was carried out to understand the fluoride ion interaction with the N-H interacting site of the ligand and its metal complexes. Furthermore, quantum chemical calculations were conducted to rationalize the interaction between chemosensors and anions. (C) 2020 Elsevier B.V. All rights reserved.
