A benzimidazole-based ‘turn-on’ fluorescent probe for highly sensitive detection of Fe3+/2+: synthesis, performance, DFT calculations and applications

A turn-on fluorescent probe (E)-2-((4-(5-fluoro-1H-benzo[d]imidazol-2-yl)benzylidene)amino)phenol (probe FBBAP) for the detection of total iron was developed. The probe alone exhibited no fluorescence but rapidly emitted blue fluorescence in EtOH with increasing...
