Abstract：
A novel squaraine derivative (SQ-1) was synthesized and characterized for the determination of cysteine. Binding with Hg2+ as a fluorescent quencher to SQ-1 leads to absorption and emission turn-off. More significantly, the SQ-1-Hg2+ complex exhibits a dual-channel chromofluorogenic responses to biologically important cysteine with a high sensitivity and selectivity over other natural amino acids, along with a low detection limit of 36.7 nM.
