Highly sensitive detection of cobalt through fluorescence changes in β-cyclodextrin-bimane complexes
A supramolecular complex of syn -(methyl,methyl)bimane ( 1 ) and β-cyclodextrin demonstrates a sensitive (limit of detection = 0.60 nM) and selective fluorescence turn-off response in the presence of cobalt in aqueous media, with calibration curves enabling quantitation in solution and using filter...

syn
-(methyl,methyl)bimane (
1
) and β-cyclodextrin demonstrates a sensitive (limit of detection = 0.60 nM) and selective fluorescence turn-off response in the presence of cobalt in aqueous media, with calibration curves enabling quantitation in solution and using filter papers on which bimane and cyclodextrin were adsorbed.
1
H NMR spectroscopy provides insight into interactions underlying the sensor performance.
Cobalt detection is accomplished
via
efficient fluorescence quenching of a bimane-β-cyclodextrin complex, both in solution and in the solid state. |
