多金属氧酸盐及其溶液自聚集行为研究进展

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。

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

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.
