This paper presents the preparation of a pyrazoline compound and the properties of its UV-Vis absorption and fluorescence emission. Moreover, this compound can be used to determine Hg(2+) ion with selectivity and sensitivity in the EtOH:H2O =9:1 (v/v) solution. This sensor forms a 1:1 complex with Hg(2+) and shows a fluorescent enhancement with good tolerance of other metal ions. This sensor is very sensitive with fluorometric detection limit of 3.85 × 10(-10) M. In addition, the fluorescent probe has practical application in cells imaging.
本文介绍了一种吡唑啉化合物的制备及其紫外-可见吸收和荧光发射性质。此外，该化合物可用于在乙醇:水 = 9:1（v/v）溶液中选择性且灵敏地测定Hg(2+)离子。该传感器与Hg(2+)形成1:1配合物，并表现出荧光增强，对其他金属离子具有良好的耐受性。该传感器非常灵敏，荧光检测限为3.85×10(-10) M。此外，该荧光探针在细胞成像中具有实际应用。
