Abstract:

Three new chemodosimeters 1–3 were prepared, and their chromogenic and fluorogenic behaviours toward various metal cations were investigated. Receptors 1–3 show an exclusive response toward Hg2+ and also distinguish Hg2+ from other metal cations by different colour changes in aqueous DMSO solution. Among them, receptor 1 also exhibits a pronounced Hg2+-induced fluorescence enhancement. Therefore, the receptor 1 can be used as a colorimetric and fluorescent chemodosimeter for the determination of Hg2+ ion.

Abstract:

Hypochlorite anion (ClO−) is a widely-used disinfectant and a microbicidal agent in the immune system. Accurate detection of ClO− in environmental and biological samples by simply prepared chemosensors/chemodosimeters is important. Herein, we report that a naphthalimide–sulfonylhydrazine conjugate with an imine (C=N) linker, prepared via simple condensation, acts as an effective fluorescent chemodosimeter for ClO−. The molecule exhibits a weak emission, but ClO−-selective cleavage of its C=N bond creates a strong green emission. Ab initio calculation showed that the emission enhancement by ClO− originates from the suppression of intramolecular electron transfer from the photoexcited naphthalimide through the C=N linker. This response enables selective and sensitive detection of ClO− at physiological pH range (7–9) and allows fluorometric ClO− imaging in the presence of cells.

Abstract:

Two novel fluorescent chemodosimeters will be presented for the selective detection of cysteine over homocysteine and glutathione in aqueous solvent. First, a rhodamine-based fluorescent probe (1) will be reported. Masked with a para-hydroxybenzyl alcohol (HBA) unit, probe 1 initially showed a weak fluorescence but displayed a strong fluorescence through a series of reactions of Michael addition and intramolecular cyclization of cysteine, followed by deprotection of HBA. The caged probe (1) exhibited a selective and sensitive response toward cysteine over homocysteine and glutathione in HEPES buffer. Secondly, a fluorescein-based fluorescent probe will be discussed. A bromoacetyl functionalized fluorescein chemodosimeter (2) was utilized as a fluorescent probe for cysteine. The probe showed a selective and sensitive response to cysteine over homocysteine and glutathione in aqueous buffer through a rapid cyclization reaction. When cysteine was added, a fast fluorescence turn-on change of 2 was observed and applied to the in-vivo imaging of cysteine.
