A novel Cu(II) complex chemosensor for hydrogen sulfide with azo as the colorimetric group has been synthesized. The complex and ligand crystals were obtained and the molecular structures were characterized by X-ray diffraction and Electrospray ionization High resolution mass spectrometer (ESI-HRMS). The photophysical and recognition properties were examined. The complex can recognize S , with an obvious color change from yellow to red based on a copper ion complex displacement mechanism. By contrast, no obvious changes were observed in the presence of other anions (AcO , H PO , F , Cl , Br and I ). We present a simple, easily prepared, yet efficient, inorganic reaction-based sensor for the detection of S . The complex should have many chemical and analytical applications in the sensing of hydrogen sulfide.
合成了一种以偶氮为比色基团的新型用于检测硫化氢的铜（II）配合物化学传感器。获得了配合物和配体晶体，并通过X射线衍射和电喷雾电离高分辨率质谱仪（ESI-HRMS）对分子结构进行了表征。研究了其光物理和识别特性。该配合物能够识别硫离子，基于铜离子配合物置换机制，颜色会从黄色明显变为红色。相比之下，在存在其他阴离子（醋酸根离子、磷酸二氢根离子、氟离子、氯离子、溴离子和碘离子）时未观察到明显变化。我们展示了一种简单、易于制备且高效的基于无机反应的用于检测硫离子的传感器。该配合物在硫化氢传感方面应具有许多化学和分析应用。
