Reversible colorimetric and NIR fluorescent probe for sensing SO2/H2O2 in living cells and food samples

A fast and specific near‐infrared fluorescent probe for hydrogen sulfide detection in aquaculture freshwater

“…The hemicyanine dye with near‐infrared (NIR) emission has been considered as preeminent fluorophore, [16] which has the characteristics of donor‐π‐receptor (D‐π‐A) conjugated system, resulting in a strong intramolecular “push‐pull” effect, that is, excited intramolecular charge transfer (ICT) [17] . In addition, the 2,4‐dinitrophenyl group is easily triggered by H 2 S‐specific thiolysis to form the dye precursor, which is accompanied by changes in fluorescence signals [18] .…”

An endoplasmic reticulum-targeted fluorescent probe for ratiometric tracking of endogenous SO2 derivatives

“…14,15 In particular, ratiometric fluorescence probes can efficiently eliminate the interferences derived from instruments, conditions and experimental operations, which ensures the precise detection of HSO 3 − /SO 3 2− . 16–19 Recently, the design mechanisms for functional fluorescent probes have been mainly based on intramolecular charge transfer (ICT), 20–23 through-bond energy transfer (TBET), 24,25 Förster resonance energy transfer (FRET), 26,27 photo-induced electron transfer (PET) 28,29 and excited-state intramolecular proton transfer (ESIPT). 30,31 Although FRET-based ratiometric probes with various superiorities such as large Stokes shift, and facile design and synthesis were developed, 32–36 ER-targeted FRET-based probes for the monitoring of HSO 3 − /SO 3 2− are rarely developed (Table S1, ESI†).…”
