多金属氧酸盐及其溶液自聚集行为研究进展

Research Progress of Polyoxometalates and Their Self-aggregation Behaviors in Solution

多金属氧酸盐(POM)是一类由过渡金属与氧原子桥连而成的阴离子簇合物,由于其特殊的分子结构及优异的物理化学性质,使其在催化、医药、材料科学、表面化学、超分子化学等领域有广泛的应用价值。POM在稀的水溶液中能够发生自聚集,形成类似两亲分子溶液中的"有序聚集体结构",赋予其新的结构和性质,以期开发出新型纳米器件及在催化、药物等领域得到应用。本文介绍了POM的主要结构、性质和近年来的应用,阐述了其在溶液中自聚集行为的研究状况和新进展。

Polyoxometalate（ POM） is an anion cluster composed of transition metal and oxygen atoms. Due to its special molecular structure and excellent physical and chemical properties,POM has a wide range of applications in catalysis,surface and supramolecular chemistry,as well as biological,pharmaceutical,and material sciences. POM in dilute aqueous solution can occur self-aggregation,forming a ＂ordered aggregates structure＂similar to the structure of amphiphilic molecule in solution,which gives new structure and property for the development of new nano-devices and in the field of catalysis,medicines and other applications. This review briefly introduced the structure,properties and applications of POM,and summarized the research status and new progress of self-aggregation of POM in solution.
