金属阳离子在生命科学和环境科学中扮演着重要的角色。在生命科学和环境检测领域,对这些金属阳离子进行定性和定量检测有着重要的意义。磷光重金属配合物以其优异的光物理性质在金属阳离子检测领域具有非常好的应用前景,如大的斯托克斯位移可以很容易区分激发和发射,长的发光寿命可使用时间分辨技术与背景荧光信号相区分以提高检测的信噪比和灵敏度以及可使用可见光进行激发等。本文总结了近年来基于重金属配合物的阳离子磷光化学传感器的研究进展。这些重金属配合物包括Pt(Ⅱ)、Ru(Ⅱ)、Re(Ⅰ)、Ir(Ⅲ)以及Au(Ⅰ)等的配合物。分别从设计原则和用于检测金属阳离子的磷光化学传感器研究进展等方面进行了阐述。最后,对用于阳离子检测的重金属配合物磷光化学传感器的研究和发展方向进行了展望。
Metal cations play an important role in life science and environmental science. In the field of life sciences and environmental testing, the qualitative and quantitative detection of these metal cations is of great significance. Phosphorescent heavy metal complexes with its excellent photophysical properties in the field of metal cation detection has very good application prospects, such as the large Stokes shift can easily distinguish between excitation and emission, long light-emitting life can use time-resolved technology and background Differentiation of fluorescent signals to improve the detection of signal to noise ratio and sensitivity and can be used to stimulate the visible light. This review summarizes recent advances in cationic phosphorescent chemical sensors based on heavy metal complexes. These heavy metal complexes include complexes of Pt (Ⅱ), Ru (Ⅱ), Re (Ⅰ), Ir (Ⅲ) and Au (Ⅰ). The design principles and the research progress of phosphorescent chemical sensors for detecting metal cations are described respectively. Finally, the research and development direction of heavy metal complexes phosphorescent chemical sensors for cation detection are prospected.
