“…According to literature reports on the recognition mechanism of SO 3 2− /HSO 3 − with fluorescent probes [ 26 , 27 , 28 ], combined with the above experimental results, it is speculated that the reaction process of probe L to recognize SO 3 2− /HSO 3 − is as shown in Figure 10 .…”

“…The bond length of C24-O2 is only 0.1234 nm, indicating that the phenolic hydroxyl group on the naphthalene ring has changed into the ketone structure (as shown in Figure 9). According to literature reports on the recognition mechanism of SO3 2− /HSO3 − with fluorescent probes [26][27][28], combined with the above experimental results, it is speculated that the reaction process of probe L to recognize SO3 2− /HSO3 − is as shown in Figure 10. Due to the influence of two strongly electron-withdrawing carbonyl groups in the probe structure, the electron cloud density of the C=C that connects 1-hydroxy-2,4-diformylnaphthalene and 1,3,3-trimethyl-2-methyleneindoline is not uniform, so it is vulnerable to attack by SO3 2− /HSO3 − and the addition reaction of C=C occurs, which destroys the original large conjugated structure.…”

A novel 1-hydroxy-2,4-diformylnaphthalene-based fluorescent probe L was synthesized by a Knoevenagel reaction and exhibited excellent sensitivity and selectivity towards sulfite ions (SO32−) and bisulfite ions (HSO3−). The detection limits of the probe L were 0.24 μM using UV-Vis spectroscopy and 9.93 nM using fluorescence spectroscopy, respectively. Furthermore, the fluorescent probe L could be utilized for detection in real water samples with satisfactory recoveries in the range 99.20%~104.30% in lake water and 100.00%~104.80% in tap water by UV-Vis absorption spectrometry, and in the range 100.50%~108.60% in lake water and 102.70%~103.80% in tap water by fluorescence spectrophotometry.

Bisulfite (HSO 3 − )/Sulfite (SO 3 2− ) is widely used as a food additive, but excessive use often leads to serious consequences, so the detection of HSO 3 − /SO 3 2− is of great importance. In this paper, a novel 1,4-diethylpiperazine-modified coumarin-benzopyran derivative (probe QLP) has been synthesized and characterized. In PBS (10 mM, pH = 7.4), QLP displays good selectivity and is sensitive for HSO 3 − /SO 3 2− over various analytes with fluorescent "OFF−ON" rapid responding (2 min), long-wavelength emission (600 nm), and a detection limit of 177 nM. With the treatment of HSO 3 − /SO 3 2− , the color of the QLP solution obviously changes from blue-green to yellow, and the fluorescent color of QLP changes from colorless to amaranth. The fluorescence-enhanced mechanism is qualitatively evaluated by density functional theory calculations using the CAM-B3LYP/6-31G (d) method, which reveals that the photoinduced electron transfer leads to the fluorescence emission of the QLP-SO 3 H adduct. Importantly, nontoxic QLP can be used to detect HSO 3 − /SO 3 2− in sugar, natural water samples, and living cells and localized to the mitochondria and monitor the mitochondrial HSO 3 − /SO 3 2− level.

“…Sulfite (SO 3 2À ), a food preservative and additive, [1][2][3] has recently been studied extensively since sulfur dioxide (SO 2 ) was identified as another endogenous gas signal molecule [4][5][6] in addition to CO, NO, and H 2 S. Because SO 3 2À /HSO 3 À are formed after SO 2 is inhaled into the body, they are commonly used as a source for studying the biological function of SO 2 . [7][8][9] Therefore, developing selective, efficient, and rapid methods for detecting SO 3 2À /HSO 3 À is critical.…”
