Based on the reversible redox reaction of 4-amino-2,2,6,6-tetramethyl-piperidin-1-ol with oxidative ClO− and reductive ascorbic acid (AA), a reversible fluorescent probe, incorporating 4-amino-2,2,6,6-tetramethyl-piperidin-1-ol group into a 7-nitrobenzoxadiazole (NBD) fluorophore, was synthesized and studied for the cyclic detection of ClO−/AA in aqueous solution. The NBD-based probe displayed sensitive...
A new turn-on fluorescent probe, incorporating 7-nitrobenzoxadiazole (NBD) ether group into a BODIPY molecule, was synthesized and studied for the detection of H2S and biothiols in aqueous solution and in living cells. The design was based on thiol-induced thiolysis of the NBD ether bond and followed by the cleavage and the release of free meso-(4-hydroxybenzyl)-substituted BODIPY fluorophore. The...
