金属有机框架(Metal Organic Frameworks,MOFs),又称多孔配位聚合物(porous coordination polymers,PCPs),是一类由金属离子和有机配体通过配体自组装形成的具有可调节孔径的新型多孔材料。由于其具有大的空隙率和比表面积,可调节的孔径以及可变的功能基团,因此广泛用于气体存储、药物运载、催化剂、光学材料和生物传感器等方面。近20年来,MOFs研究获得高速发展。通过高频关键词和高被引文献分析了MOFs领域近年的研究热点及趋势,为今后的研究提供参考。
Metal Organic Frameworks (MOFs),which are also called porous coordination polymers(PCPs),are a class of crystalline materials built from metal ions and organic binding ligands through self-assembly.MOFs have high porosity,large specific surface areas,adjustable pore size and variable functional groups.Thus many potential applications have been proposed in the domains of gas adsorption,drug delivery,catalysis,optical materials,sensors or others.Over the past two decades,the research of MOFs has developed rapidly.Based on key word frequency and highly cited papers analysis,the hot research topics and trends of MOFs in recent years were discussed,providing reference for future research.
