Description
Technical Field
The invention belongs to the technical field of chemical analysis and test, and particularly relates to a benzindole squaraine metal ion probe, and a preparation method and application thereof.
Background
Iron and copper are two microelements necessary for the human body and play an important role in many vital activities. Iron is involved in the processes of oxygen transport and proton transfer in blood, and is an important component of various enzymes and hemoglobin; once the iron element in the human body is deficient, the physiological function system is disturbed, thereby causing diseases; while excess iron is potentially harmful, it may promote oxidation of fats, proteins and other components of the cell to become toxic. Likewise, the lack or excess of copper ions in the body can also lead to disturbances in growth and metabolism, leading to serious disorders of copper metabolism. In addition, mercury is a heavy metal element with high toxicity to humans and the environment, and its accumulation in the body causes serious health problems. Therefore, the development can efficiently and selectively detect Fe in natural environment and organism 3+ 、Cu 2+ 、Hg 2+ Is of interest. Detection goldThe traditional methods of the genus ion are: atomic absorption spectrophotometry, inductively coupled plasma atomic emission spectrometry, electrochemical analysis, and the like. The above methods often require the use of expensive instrumentation and specialized inspectors, which are not suitable for mass and real-time inspection. The fluorescent probe detection method has the advantages of high sensitivity, low cost, easiness in operation and the like. Currently used for detecting Fe 3+ 、Cu 2+ 、Hg 2+ The fluorescent probe molecules of (2) often have the defects of complex preparation, low selectivity, insufficient absorption and emission wavelength, and the like. Therefore, the probe molecule with high sensitivity, high selectivity and strong absorption and fluorescence emission in the near infrared region is developed to detect Fe in natural environment and organism 3+ 、Cu 2+ 、Hg 2+ It is important.
Squaraine is a D-A-D conjugated organic molecule formed by condensing two identical or different electron-rich electron-donating units (donor, D or D') and a strong electron-withdrawing squaraine unit (A), and has a zwitterionic structure with stable resonance. Most squaraines absorb and emit strongly in the visible and near infrared regions with molar extinction coefficients (. Epsilon.) of up to 10 5 M -1 cm -1 The method comprises the steps of carrying out a first treatment on the surface of the And squaraine has the advantages of easy aggregation, simple synthetic route, good photo/thermal stability, strong structural modification, and the like.
