1,2,3-Triazole-imidazole derivatives (TA-IM) were prepared as fluorescent probes for silver ion 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 the 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 (in the nM range) with good linear correlation, making it a practical sensor for detection of silver ions.

三唑-咪唑 (TA-IM) 衍生物作为超快荧光探针用于选择性 Ag+ 检测



制备了1,2,3-三唑-咪唑衍生物(TA-IM)作为银离子检测的荧光探针。设计原理是在咪唑和三唑部分之间引入分子内氢键,从而实现共面构象,从而实现紫外蓝色范围内的荧光发射。对不同金属离子的筛选表明,这类新型化合物对水溶液中的银离子具有优异的结合亲和力。即使对于非常低浓度的银离子(在nM范围内),新型探针也能提供超快检测(<30 s),并具有良好的线性相关性,使其成为检测银离子的实用传感器。
