金属有机框架材料荧光检测重铬酸根研究进展

Research Progress of Fluorescent Probes for the Detection of Cr_(2)O_(7)^(2-) based on Metal Organic Frameworks

综述了基于过渡金属离子、其他金属离子构筑的MOFs和稀土有机框架材料(LnMOFs)作为荧光探针对水中污染物重铬酸根离子的检测进展,对其各自的特点进行了讨论。在此基础上,提出MOFs对重铬酸根离子的荧光检测机理。制备稳定性高、成本低、可多次重复使用重铬酸根离子MOFs荧光探针是今后的研究方向。

The progress in the detection of dichromate ion in water by employment metal organic frameworks(MOFs)based transition metal ions and other metal ions and lanthanide-based metal organic frameworks(Ln-MOFs)as fluorescence probes was reviewed,and their respective characteristics were discussed in detail.On this basis,the fluorescence detection mechanism of dichromate ion by MOFs was proposed.The preparation of luminescent MOFs probes for detection of Cr_(2)O_(7)^(2-)-ions with high stability,low cost and reused many times is the future development direction.
