【摘要】 钒氧簇是多金属氧簇的一个重要分支。由于钒氧簇具有多样的结构、优良的物理特性,使得其在催化、磁性及光学材料等方面具有广阔的应用前景,引起了人们的日益关注。将主族的金属或非金属元素引入到钒氧簇体系,可以形成结构新颖的取代型钒氧簇。新颖构型及其拓展结构取代型钒氧簇合物的合成,极大地丰富了钒氧簇的结构类型,推动了钒氧簇合成化学的持续发展。该类化合物在磁性方面有着潜在的应用前景。本文总结了近十年来取代型钒氧簇合物的研究成果,综述了已有化合物的磁学性质,并对其今后研究前景进行了展望。更多还原

【Abstract】 Vanadium-oxide clusters are one class of the most important polyoxometalates.The design and assembly of polyoxovanadates(POVs) are currently of great interest in the field of crystal engineering,not only because of their structural diversity,but also their potential applications in the fields of catalytic,magnetic and optical materials.To date,a brand-new class of POVs with the incorporation of main group elements into vanadium-oxide clusters has been widely investigated.In recent years,transition-metal complexes(TMCs) are utilized to combine with different substituted vanadium-oxide clusters for the construction of various novel structural types with desired properties,which not only greatly enriched the structure of vanadium-oxide clusters,but also promoted its continuous development in the synthesis.A review has been mainly given to the new development of the substituted vanadium-oxide clusters in the aspects of structural characteristics and magnetic properties over the past several years.The prospects of them are also discussed in this paper.更多还原
