A novel turn-on fluorescent probe (DDND) for highly selective detection of biothiols over other amino acids was synthesized and investigated in this work, which used the 2,4-dinitrobenzenesulfonyl group as a fluorescent quencher.
A novel hemicyanine-based fluorescent probe was developed for the fast, selective, and reversible detection of Cu2+ ions with “turn-on” fluorescence response in the aqueous solution.
A water-soluble fluorescent probe for Zn2+based on a Schiff base derivative was prepared. It displays a rapid response toward Zn2+with selectivity and sensitivity and has been successfully applied to imaging in living cells.
A new type of AIE-based turn-on fluorescent probe 1 was reported to highly selective detection of NO3− anion in aqueous solution and living cells by virtue of ionic interaction.
