Synthesis of novel benzophenone-based chemosensor is presented for the selective sensing of Sn ion. Screening of competitive metal ions was performed by competitive experiments. The specific cation recognition ability of chemosensor towards Sn was investigated by experimental (UV-visible, fluorescence spectroscopy, H NMR, C NMR, FTIR and HRMS) methods and further supported by Density Functional Theory study. The stoichiometric binding ratio and binding constant (K) for complex is found to be 1:1 and 1.50×10, respectively. The detection limit of Sn towards chemosensor was found to be 0.3898ppb. Specific selectivity and superiority of chemosensor over another recently reported chemosensor is presented.
本文介绍了一种新型二苯甲酮基化学传感器的合成，用于选择性检测锡离子。通过竞争性实验对竞争性金属离子进行了筛选。采用实验方法（紫外可见光谱、荧光光谱、核磁共振氢谱、核磁共振碳谱、傅里叶变换红外光谱和高分辨质谱）研究了化学传感器对锡的特异性阳离子识别能力，并通过密度泛函理论研究进一步提供了支持。发现配合物的化学计量结合比和结合常数（K）分别为1:1和1.50×10。发现化学传感器对锡的检测限为0.3898ppb。本文展示了该化学传感器相对于另一种最近报道的化学传感器的特异性选择性和优势。
