incubated with 1, a marked increase in green emission (Figure
3B4) and a slight decrease in blue emission (Figure 3A4) were
observed. These results are in agreement with the specificity of
probe 1 for Cys or GSH and also demonstrate the potential of
1 to sense intracellular Cys and GSH simultaneously from
different emission channels. In addition, the MTT assay for 1
was also conducted, and the results showed that the probe at a
concentration of 10 μM has only minimal cytotoxicity (Figure
S18).
Finally, we also evaluated how the mixture of Cys/Hcy/GSH
affects the emission of 1 (10 μM) in vitro. It was found that
addition of the high concentration of Cys/Hcy/GSH (100 μM/
100 μM/1 mM) to 1 could elicit the obvious fluorescence turn-
on at 420 nm (for Cys) excited at 360 nm (Figure S19A1), but
almost no fluorescence changes at 512 nm (for GSH) excited at
450 nm. This could be attributed to the higher reactivity of Cys
than GSH. However, in the presence of the low concentration
of biothiol mixture (Cys/Hcy/GSH: 1/1/10 μM), GSH could
elicit the obvious fluorescence turn-on at 512 nm excited at 450
nm (Figure S19B1). These results indicated that probe 1 could
selectively detect Cys or GSH in the presence of other
biothiols.
In summary, we have presented a chlorinated coumarin-
hemicyanine fluorescence probe 1 that can selectively sense Cys
and GSH from different emission channels. We also
demonstrated that probe 1 is able to simultaneously monitoring
Cys and GSH in COS-7 cells in multicolor imaging. All these
results are based on three reaction sites of probe 1, which elicit
three different chemical reactions toward Cys, Hcy, and GSH,
respectively. We hope that the novel strategy could inspire the
exploration of new systems to sense biothiols with improved
sensitivity, greater fluorescence turn-on or ratiometric response
for probing biothiols function in biological systems.

reaction of 1 with Cys (or GSH) is extremely slow.
