“…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 †). 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 †).…”
