摘要
汞广泛存在于各类环境中,全球发展了较多类型的汞荧光分子传感器。相比有机传感器而言,过渡金属有机配合物具有立体结构丰富,水溶性好,Stokes位移大,选择性强和灵敏性高,发光寿命长以及生物毒性小等优点。而基于过渡金属有机配合物的金属有机框架材料(MOFs),还具有可调的孔径结构和丰富的官能团种类,有着广泛的应用前景。介绍了部分近年来报道的应用于汞荧光分析传感的过渡金属配合物,通过对其中亮点工作的详述,展示当前该技术的研究水平以及存在的问题,并提出了未来发展方向。
As a highly toxic element,the mecury presents extensively in various environments,and many types of mercury fluorescent sensors have been developed worldwide.Compared to organic probes,organotransition metal complexes have many advantages,such as containing rich stereo structures,good water solubility,large stokes shift,high selectivity and sensitivity,long luminous lifetime and low biological toxicity.Metal-organic frameworks(MOFs)which derive from organotransition metal complexes have adjustable pore structure and rich species of functional groups and can be applied in many fields.This article summarizes some organotransition metal complexes for mercury fluorescence analysis developed in recent years through detailing the highlights of these works and putting forward the future development directions.
