摘 要:金属-有机框架材料(Metal-Organic Frameworks,MOFs),又称为多孔配位聚合物(Porous Coordination Polymers,PCPs),是由金属离子与多齿有机配体通过配位键组装形成的网状结构的配位聚合物。由于具有比表面积高、热稳定性、机械稳定性和化学稳定性好和孔的可调性等特性,使其在样品前处理领域显示出了诱人的应用前景。本文主要介绍了金属-有机框架材料在样品前处理中的应用研究,主要包括在样品采集与预富集、固相萃取、微固相萃取中的应用研究进展。Metal -organic frameworks (MOFs), also called porous coordination polymers (PCPs), were organic - inorganic hybrid solids with infinite, uniform framework structures built from organic linkers and inorganic metal nodes via coordination bonds. Owing to the high surface area, good thermal stability, mechanical, chemical stability and tunable cavity, MOFs exhibited the attractive prospects in sample preparation. The main progresses made in the field of MOFs for sample preparation were reviewed and summarized. In order to get comprehensive understanding of the MOFs for sample preparation, the development of sampling and preconcentration, solid - phase extraction and micro - solid - phase extrac- tion was focused.
