Triazole-Imidazole (TA-IM) as Ultrafast Fluorescent Probes for the Selective Silver Detection

Abstract

The 1,2,3-triazole-imidazole derivatives (TA-IM) were prepared as fluorescent probes for silver ions detection. The design principle is the incorporation of an intramolecular H-bond between the imidazole and triazole moiety that enables a co-planar conformation to achieve fluorescence emission in UV-blue range. Screening of different metal ions revealed excellent binding affinity of this new class of compounds toward silver ions in aqueous solution. The novel probe provided ultrafast detection (< 30 s) even for a very low concentration of silver ions (at nM range) with good linear correlation, making it a practical sensor for detection of silver ions.
