Xu, Li published the artcileA highly selective and sensitive photoswitchable fluorescent probe for Hg2+ based on bisthienylethene-rhodamine 6G dyad and for live cells imaging, Synthetic Route of 219537-97-0, the publication is Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (2014), 567-574, database is CAplus and MEDLINE.
A new photochromic diarylethene derivative bearing rhodamine 6G dimmer as a fluorescent mol. probe is designed and synthesized successfully. All the compounds are characterized by NMR and mass spectrometry. The bisthienylethene-rhodamine 6G dyad exhibit excellent phtochromism with reversibly color and fluorescence changes alternating irradiation with UV and visible light. Upon addition of Hg2+, its color changes from colorless to red and its fluorescence is remarkably enhanced. Whereas other ions including K+, Na+, Ca2+, Mg2+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+, Mn2+, Pb2+, Ni2+, Fe3+, Al3+, Cr3+ and so on induce basically no spectral changes, which constitute a highly selective and sensitive photoswitchable fluorescent probe toward Hg2+. Furthermore, by means of laser confocal scanning microscopy experiments, it is demonstrated that this probe can be applied for live cell imaging and monitoring Hg2+ in living lung cancer cells with satisfying results, which shows its value of potential application in environmental and biol. systems.
