New Colorimetric Chemosensor for Rapid Naked-Eye Detection of Cu2+ and Its Application in Gas-Generating Agents.
In this work, a new rhodamine derivative R1 was constructed to act as a highly effective colorimetric chemosensor for Cu2+ ions. The introduction of Cu2+ could lead to the formation of 1:1 metal-ligand complex and the rhodamine ring-opening process. Resultantly, R1 displayed marked absorbance and fluorescence enhancement with the addition of Cu2+ ions. Furthermore, there was a good linear relationship between the absorbance intensity change and the concentration of Cu2+ ions, which was beneficial for the exactly quantitative detection. R1 could serve as practical colorimetric sensors for "in-the-field" measurements that would not require any additional equipment by virtue of "dip-sticks" approach. Especially, the efficient detection of Cu2+ with R1 for the practical application was successfully performed in gas-generating agents detection.
期刊介绍：
Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
