Fig. 5 Imaging of A549 cells with hydrazine (1 mM), compound 1 (10 mM)
before and after the addition of hydrazine (lex = 405 nm, lem = 470 Æ
20 nm, pseudocolor green, green channel; lem = 580 Æ 20 nm, pseudo-
color red, red channel). Scale bar: 20 mm.
To further develop the application of probe 1 in the detection of
hydrazine in A549 cells and HeLa cells, a cytotoxicity test was firstly
performed. As can be seen from the Fig. S14 (ESI†), when the probe
concentration reaches 25 mM, both A549 and HeLa cells still
maintain a survival rate above 80%. As shown in Fig. 5, after
adding 1 mM hydrazine to A549 cells, neither the green channel
(lem = 470 Æ 20 nm) nor the red channel (lem = 580 Æ 20 nm)
shows any fluorescent signal. When 10 mM of probe 1 is added to
A549 cells, the cells show a strong fluorescence signal in the red
channel and an extremely weak fluorescence signal in the green
channel. And when the cells are cultured with 10 mM of probe 1 and
500 mM of hydrazine, it is found that the fluorescent signal in the
red channel is obviously attenuated, while the fluorescent signal in

further strengthened, thereby achieving the identification of hydra-
zine in the cell.
In summary, based on the good photophysical properties of
coumarin derivatives and their wide application in chemical
sensing, coumarin chalcone compound 1 was developed.
By comparing the recognition effects of compounds R-OH, R
and 1 on hydrazine, we found that the substituted groups on
the terminal benzene rings of compound R-OH (hydroxyl group)

of hydrazine. Moreover, compared with compound R-OH, probe 1
is more advantageous in terms of sensitivity, time response, and
quantum yield. Based on the fact that probe 1 can recognize
hydrazine in the range of pH 3.0–12.0 and has low cytotoxicity,
we explored the application of the probe in cell imaging and found
