A novel ratiometric fluorescent probe based on thieno[3,2-c]coumarin has been prepared for sensing hypochlorite, which could exhibit a large emission shift and a 338-fold emission ratio (I470/I640).
Selectively probing Zn2+in vivo! A new fluorescent probe highly sensitive and selective for Zn2+ based on the ICT effect was designed. This probe showed potential application in biology.
