Abstract
Triazole Schiff base as fluorescent chemosensor and fluorogenic cation sensor is crucial for the detection of metal ions. The diverse structures of triazole Schiff bases have raised concerns. Excellent luminous properties are produced by mixing donor and acceptor groups with delocalized π-orbitals due to the intramolecular charge transfer (ICT) mechanism. For Al3+ metal ions, this work provides data on the triazole Schiff base, design, synthesis, and sensing mechanism (ON/OFF, OFF/ON, and ON-OFF-OFF) of these sensors, as well as their potential uses. We also examined how the sensor's photophysical characteristics alter when it coordinates with the metal ions, leading to modifications in its usual sensing behaviour, such as a shift from hypsochromic/bathochromic or hypochromic/hyperchromic. Researchers will use this review as a starting point to investigate triazole Schiff base-based sensors further.
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.
