Fig. 11. Fluorescence emission changes of compound 1 (5 M) upon addition of
TBAF and NaF (2000 equiv.) in DMSO/H2O (95:5, v/v) (excited at 365 nm).
ple, it needs 50 equiv. of F− to reach saturation in pure DMSO but
about 1500 equiv. in DMSO/H2O (95:5, v/v) when the concentra-
tion of 1 is 5 M. Therefore, it is better to use pure DMSO as solvent
when detecting F−.
Another advantage of this prober is of possible in detection of
the NaF, which is rarely reported in literatures. The fluorescence
emission of compound 1 was increased about 337-fold upon addi-
tion of 2000 equiv. of NaF in DMSO/H2O (95:5, v/v), only a little
lower compare to addition of same equiv of TBAF (see Fig. 11).

We report a new pyrazole-based fluorescent compound suitable
for floride sensing over other anions in DMSO. It is a very good naked
eye “no–yes” detection sensor for the fluoride anion. Studies with
spectroscopic techniques indicate that the mechanism of the anion
recognition is the deprotonation of the pyrazole–NH. Compound 1
is also a good sensor in DMSO aqueous solution for the detectin of
floride anion (TBA+ and Na+ salts).
