A naphthalimide-based glyoxal hydrazone for selective fluorescence turn-on sensing of Cys and Hcy.

A fluorescent turn-on probe for Cys/Hcy based on inhibiting the C═N isomerization quenching process by an intramolecular hydrogen bond was reported. The probe exhibited higher selectivity toward Cys/Hcy over other amino acids as well as thiol-containing compounds.

Ratiometric fluorescence detection of cyanide based on a hybrid coumarin–hemicyanine dye: the large emission shift and the high selectivity

A new ratiometric fluorescent cyanide probe was developed based on the nucleophilic attack of CN(-) toward the indolium group of a hybrid coumarin-hemicyanine dye, by which high selectivity as well as large emission shift could be achieved.

A fluorescent turn-on probe for bisulfite based on hydrogen bond-inhibited CN isomerization mechanism

A fluorescence turn-on probe for bisulfite has been developed by taking advantage of the specific reaction of bisulfite and aldehyde in combination with the hydrogen bond inhibited C=N isomerization mechanism. The practical value of this selective and sensitive fluorescent probe was confirmed by its application to detection of bisulfite in granulated sugar.

A ratiometric fluorescent probe for cyanide based on FRET

On the basis of FRET from 4-(N,N-dimethylamino)benzamide to fluorescein, a new ratiometric fluorescence probe bearing a hydrazone binding unit was developed for highly selective and sensitive detection of CN(-) in aqueous solution.

A Cu(II)-based chemosensing ensemble bearing rhodamine B fluorophore for fluorescence turn-on detection of cyanide

A Cu(II)-based 2 : 2 chemosensing ensemble bearing rhodamine B fluorophore was developed for fluorescence turn-on detection of CN− with high selectivity and sensitivity based on the CN− complexation to the Cu2+ centre in the nearly planar central binding moiety.

D-Luciferin Analogues: a Multicolor Toolbox for Bioluminescence Imaging†

Colorful mixture: Three types of luciferin analogues, that is, alkylaminoluciferins, aminoselenoluciferin, and luciferins with a benzimidazole scaffold, have been reported. These analogues show excellent bioluminescent properties and great potential in bioluminescence imaging.
