The invention provides a novel ligand for copper ion detection and preparation thereof, a novel ruthenium complex and a near-infrared long-life fluorescent probe. The results show that the complex prepared by the ligand provided by the invention has an emission wavelength in the near range Infrared region, long excited state lifetime, good biocompatibility, can be used as a fluorescent probe or test paper for the detection of copper ions in vitro, and can also be used as a fluorescent probe for the detection of copper ions in vivo, and then used in life science research In addition, the complex has a simple preparation method, is suitable for industrial production, and has a good industrial application prospect. |
