4-Quinolone-Carboxamide and Carbothioamide Compounds as Fluorescent Sensors. New Fluorimetric Methods for Cu2+ and Fe3+ Determination in Tap Water and Soil

Artificial light-harvesting nanoparticles based on a tripodal fluorescence sensor mediated by multiple luminescence mechanisms

“…In addition, the fluorescence limit of detection (LOD) of G were calculated as 4.35 × 10 −7 M for Fe 3+ and 5.10 × 10 −7 M for Cu 2+ , which are comparable to those reported in the literature. [70][71][72][73] Furthermore, the Job's plot for G with Fe 3+ and Cu 2+ were depicted. The Job's plot of G and Cu 2+ showed a stoichiometry of 1 : 1 (Fig.…”

A Fluorescent Chemosensor for Detection pH and Cu2+ Ion Base on 7-((2-Aminoethyl)amino)-5-Bromo-6-Hydroxy-1-Methylquinolin-1-ium-3-Sulfonate: Experimental and DFT Calculation

“…Quinoline derivatives are one of the effective groups of compounds applied in uorescent detectors. A considerable number of quinoline compounds, while bonding speci c functional groups such as phenol, aromatic amine, saturated amine, hydrazine, ... showed potential application in selected and sensitive analysis protons and several metal cations like Cu 2+ , Fe 3+ , Zn 2+ with the low LOD [8,9]. However, the bulky structures make it di cult to dissolve these compounds in water and sensor insides human body, so investigating more preeminent quinolines is still an important research eld.…”
