Abstract:
A new design strategy for the construction of ratiometric fluorescent probe with a large emission shift was developed. Based on this strategy, a highly selective and sensitive colorimetric and ratiometic fluorescent probe for cysteine (Cys) with a 117 nm red-shifted emission was synthesized and applied to the ratiometric imaging of endogenous Cys in living cells.
