| titleOfInvention | Amide group-containing fluorescent probe for Hg2+And methods of use |
| abstract | The invention discloses Hg containing an amide group 2+ Fluorescent probes and methods of use. The invention aims to solve the problems that the existing fluorescent probe for identifying mercury ions has complex synthesis, poor water solubility, narrow applicable pH range, low selectivity and easy exposure to other cations (Au) 3+ ，Fe 2+ ，Fe 3+ And Cu 2+ ) The problem of interference. We have found that the probes of the invention are capable of reacting with Hg in an aqueous HEPES solution 2+ Form stable complex and quench the fluorescence of the host probe. Under experimental conditions, the common metal ion pairs Hg 2+ No significant interference was detected. For Hg 2+ The pH value suitable for detection is 2.0-11.8, the response time is 14min and Hg 2+ The detection limit of (a) can reach 0.65 nM. The amide group-containing fluorescent probe can detect Hg in aqueous solution by fluorescence 2+ Green and environment-friendly, and has extremely high application value. |
