An Experimental and Quantum (QTAIM) Performance Study of a Proposed Molecular Chemosensor: A Quinazolinone‐Based Sensor for Hg2+ Ion Detection

Abstract: This work synthesized a novel colorimetric ligand based on the compound quinazolinone (Sensor) and investigated it. The sensing activity of the sensor toward different cation was studied. The sensor demonstrated a highly selective colorimetric sensing toward Hg 2 + with a detection limit of 0.1 ppb and visual color change from colorless to Purple in methanol-water solvents (v/v, 10,90). The cation binding character was determined using visual inspection, UV-Vis, and fluorescence analyses. In the computational … Show more
