Cysteine (Cys), homocysteine (Hcy) and glutathione (GSH), the small molecule biological thiols, play essential roles in maintaining human biological systems. Research of quantitative determination of biothiols is always significant. We have designed and synthesized a fluorescent probe ANBI based on a naphthalene-benzo[g]indol-1-ium scaffold, quick respond to biothiols in water. The probe exhibits...
A readily available coumarin–quinoline was employed as a novel fluorescent probe for paramagnetic Co 2+ and Ni 2+ ions, which are well-known fluorescence quenchers. NMR and IR indicated that the enhanced fluorescence response was attributable to coordination of the paramagnetic Ni 2+ or Co 2+ ions with the coumarin–quinoline compound. Given the difficulty of designing...
