Heavy metal pollution has become one of the most significant pollution problems encountered by our country in terms of environment protection. In addition to the significant effects of heavy metals on the human body and other organisms through water, food chain enrichment and other routes, heavy metals involved in daily necessities beyond the level limit could also affect people's lives, so the detection of heavy metals is extremely important. Ir (III) coordination compound, considered to be one of the best phosphorescent sensing materials, is characterized by high luminous efficiency, easy modification of the ligand and so on, and it has potential applications in the field of heavy metal detection. This project aims to product a new Ir (III) functional coordination compound by designing a new auxiliary ligand and a main ligand with a sulfur identification unit, in order to systematically investigate the application of iridium coordination compound in the detection of the heavy metal Hg. With the introduction of the sulfur identification unit, selective sensing of Hg could be achieved. Additionally, a new auxiliary ligand is also introduced to produce a functional iridium coordination compound with high quantum efficiency, and to diversify the application of iridium coordination compound in this field.
重金属污染已成为我国环境保护面临的最重要污染问题之一。除了重金属通过水、食物链富集等途径对人体和其他生物产生重大影响外，日常用品中重金属含量超标也会影响人们的生活，因此重金属检测极为重要。铱（III）配位化合物被认为是最佳的磷光传感材料之一，具有发光效率高、配体易于修饰等特点，在重金属检测领域具有潜在应用价值。本项目旨在通过设计一种带有硫识别单元的新型辅助配体和主配体，制备一种新型铱（III）功能配位化合物，以便系统研究铱配位化合物在重金属汞检测中的应用。通过引入硫识别单元，可实现对汞的选择性传感。此外，还引入一种新型辅助配体，以制备具有高量子效率的功能性铱配位化合物，并使铱配位化合物在该领域的应用更加多样化。
