Abstract
We report a water-soluble turn-on type diarylethene SO3-BPDBTEO that reversibly switches its fluorescence on and off upon light stimuli. We note that the two sodium sulfonate groups enable SO3-BPDBTEO to exhibit excellent photo-switching properties in aqueous solution over a wide range of pH between 3 and 10. We demonstrated that SO3-BPDBTEO could be applied to conventional fluorescence imaging of mammalian cell lines such as HeLa cell at various pH conditions with low cytotoxicity. We also examine its feasibility for super-resolution fluorescence imaging as a photoswitching probe.
