A “Turn-On” Fluorescent Probe for the Visual Detection of Total Iron in Wine
A turn-on fluorescent sensor (E)-4-((4-(5-fluoro-1H-benzo[d]imidazol-2-yl)benzylidene)amino)phenol (FBAP) for the detection of Fe3+/2+ was synthesized. The fluorescence intensity of probe FBAP solution gradually increased with increased Fe3+ concentration. The low detection limit (LOD) was calculated to be 0.17 nM. The optimized structure and luminescent properties of FBAP were calculated by time-dependent density functional theory (TD-DFT) and Solvation Model Density (SMD). The rotation of the dihedral angle and ICT in the imine probe turned off the emission of the benzimidazole, which was restored upon cleaving the imine. Probe FBAP was successfully applied to determine whether Fe3+/2+ in wine exceeded the standard by phone and the rapid detection of Fe3+/2+ in the form of test strips was also conducted.
期刊介绍：
Luminescence provides a forum for the publication of original scientific papers, short communications, technical notes and reviews on fundamental and applied aspects of all forms of luminescence, including bioluminescence, chemiluminescence, electrochemiluminescence, sonoluminescence, triboluminescence, fluorescence, time-resolved fluorescence and phosphorescence. Luminescence publishes papers on assays and analytical methods, instrumentation, mechanistic and synthetic studies, basic biology and chemistry.
Luminescence also publishes details of forthcoming meetings, information on new products, and book reviews. A special feature of the Journal is surveys of the recent literature on selected topics in luminescence.
