Deciphering of Ligand‐to‐Metal Charge‐Transfer Process: Synthesis, Spectroscopic and Theoretical Study

Abstract: Many reports on metal ion sensing applications are available in literature but the mechanism of selectivity is not clear. Here the synthesis and characterization of a Schiff base Furan‐2‐carboxylic acid pyren‐1‐ylmethylene‐hydrazide (PYFH) has been described with selective detection of copper(II) metal ion among different metal ions by UV–vis, fluorescence and HRMS spectroscopic methods. The S2− ion (Na2S) was added to the PYFH:Cu2+ complex for checking reversibility of PYFH by fluorescence, fluorescence micro… Show more

“…Metal-ligand charge transfer (MLCT): Involves the transfer of electronic charge between a metal ion and a ligand, as the d orbitals of the metal atom and the ligand orbitals (p, d, or f, depending on the type of ligand) can overlap. It predominantly occurs in metal complexes [97]. c.…”
