A novel red (λmaxem = 632 nm) fluorescent probe based on 3-hydroxyflavone was designed and synthesized for thiol recognition with high sensitivity and excellent selectivity. Application of the probe for selective detection of intracellular thiols has been successfully demonstrated. © The Royal Society of Chemistry 2013.

A colorimetric and ratiometric fluorescent sulfite probe, the levulinate of 4-hydroxynaphthalimide, was successfully synthesized from 4-hydroxy-naphthalimide and levulinic acid. Through sul fite-mediated intramolecular cleavage, the probe was converted into 4-hydroxynaphthalimide, which when excited at 450 nm, displayed a large Stokes shift due to the intramolecular charge transfer process. The probe exhibited high selectivity and sensitivity towards sulfite over other typical anionic species (F-, Cl-, Br-, I-,HPO4 2-,SO4 2-, NO3 -, AcO-,ClO4 -,HCO3 -) in HEPES-buffered solution (25 mM, pH 7.4, 50% acetonitrile, v/v).

A novel red emitting fluorescent probe exhibiting a 143 nm Stokes shift for the detection of fluoride ions in an aqueous solution was developed. The probe displays a rapid response, high selectivity and good sensitivity towards F -. Application of the probe for the selective detection of intracellular F- has been successfully demonstrated in living cells. © 2013 The Royal Society of Chemistry.

A red-emitting fluorescent probe for selective detection of cysteine was developed based on the conjugated addition/cyclization sequence mechanism. Upon the treatment with cysteine, this probe exhibits a strong fluorescence enhancement (62-fold) and a large Stokes shift (148 nm). The detection limit was calculated to be as low as 6.6 nM based on S/N = 3. Importantly, the practical application of this probe for the selective detection of cysteine was successfully demonstrated in living cells. © 2016 Published by Elsevier B.V.

A colorimetric and turn-on fluorescent probe for fluoride ions, tert-butyldimethylsilane 6-acetyl-2-naphtholate, was readily synthesized from 6-acetyl-2-naphthol and tert-butyldimethylchlorosilane (TBSCl). The probe exhibits high sensitivity and good selectivity for fluoride ions in acetonitrile. The inherent mechanism involves the cleavage of the Si-O bond in the probe, which induced yellow color formation and prominent fluorescence enhancement. Copyright © 2013 John Wiley & Sons, Ltd.
