Dual signaling of thallium(III) ions via oxidative cleavage of a sulfonhydrazide linkage

The thallium is widely used in various research and industrial applications but is very toxic. In this work, we developed a novel reaction-based dual signaling probe for the selective and sensitive determination of Tl3+ via the oxidative cleavage of a rhodamine–dansylhydrazide conjugate. The designed probe showed pronounced colorimetric and fluorescence signaling behavior toward Tl3+ with a detection limit of 1.3 × 10–7 M (0.027 ppm), as well as selectivity over other common metal ions, anions, and oxidants. The Tl3+ signaling process required less than 2 min and was not influenced by the solution pH within the range of 4.0–5.5; however, the signal diminished significantly above pH 6.0. To demonstrate the practical applicability of the designed probe, a simple and convenient colorimetric assay for the determination of Tl3+ in commercial reagents was established using an office scanner as a readily available signal capturing device.

Activation of fluorescence of lactone forms of rhodamine dyes by photodehydrogenation of aryl(hetaryl)pyrazolines

Aryl(hetaryl)pyrazolines are effective photogenerators of acid providing an irreversible photochemical activation of fluorescence of rhodamine group dyes. The effect of solvent on two consecutive reactions, photodehydrogenation of pyrazoline and lactone ring opening of the dye was studied. An increase in solvent polarity leads to an increase in the rate of both reactions by different degrees. The systems under study are believed to be promising for the formation of recording media for multilayer optical file type disks of ultrahigh data storage capacity with fluorescent readout.

Sulfonyl rhodamine hydrazide: A sensitive and selective chromogenic and fluorescent chemodosimeter for copper ion in aqueous media

A novel, sulfonyl rhodamine hydrazide chemodosimeter displayed highly selective and sensitive recognition of Cu2+ in aqueous media, via colour change from colorless to pink. The colour change that occurred as a result of complexation with Cu2+ can be attributed to spirolactam ring-opening and hydrolysis of the hydrazide unit to afford C.I. Acid Red 52 (Rhodamine B) in the presence of Cu2+. An analytical method was developed and successfully used for the determination of the copper content in a sample.
