| dc.description.abstract | A naphthaldehyde appended sensor has been synthesized and characterized by spectroscopic techniques. The sensor has been efficiently utilized in selective chromogenic detection of Cu2+ in aqueous ethanol amongst various metal ions. Cu2+ interacts with the sensor in 1:2 (M:L) stoichiometry with binding constant of 1.1 × 103 M−1/2 and detection limit of 9.342 × 10−7 M. Ligand to metal charge transfer (LMCT) accounts for the selective color change from colorless to yellow with Cu2+ as suggested by UV–Vis and DFT studies. This sensor offers certain advantages over the existing chemosensors in terms of reversibility, reusability and solid state applications. © 2021 Elsevier B.V. | |
