Abstract: | A ratiometric fluorescence and colorimetric probe based on 5,5′-methylene-bis-salicylaldehyde-p-nitrophenylhydrazone (1),
which was characterized by 1H NMR, mass spectrometer and elemental analysis, was prepared through Schiff base reaction. The probe exhibited visible color
changes from yellow to purple upon interacting with acetate ion. Particularly, the compound showed ratiometric fluorescence
response to acetate with significant blue shift about 150 nm from 410 nm to 560 nm. Thence, the probe 1 was a selective ratiometric
fluorescence probe for acetate ion in DMSO solution. |
