A novel ratiometric sensor prepared based aggregation-induced emission for ultrafast detection of SO2 derivatives in food samples and living cells

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

“…JSS-1 exhibited various spectra in different solvents, which can be attributed to the polarity of the solvent and the intermolecular interactions between the probe and solvent molecules. 42,50 The photostability of probe JSS-1 in vitro was evaluated by continuous exposure in dark, natural light and excitation light (400 nm) conditions (Fig. S7, ESI†).…”

“…The fluorescence properties of probe JSS-1 in various solvents were researched, including dichloromethane (DCM), N,N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), ethyl acetate (EA), ethanol (EtOH), acetonitrile (MeCN), methanol (MeOH) and tetrahydrofuran (THF) (Fig.S6, ESI †).
