Abstract

Polyoxovanadate (POV) clusters are an important subclass of polyoxometalates with a broad range of molecular compositions and physicochemical properties. One relatively underdeveloped application of these polynuclear assemblies involves their use as atomically precise, homogenous molecular models for bulk metal oxides. Given the structural and electronic similarities of POVs and extended vanadium oxide materials, as well as the relative ease of modifying the homogenous congeners, investigation of the chemical and physical properties of pristine and modified cluster complexes presents a method toward understanding the influence of structural modifications ( crystal structure/phase, chemical makeup of surface ligands, elemental dopants) on the properties of extended solids. This review summarises recent advances in the use of POV clusters as atomically precise models for bulk metal oxides, with particular focus on the assembly of vanadium oxide clusters and the consequences of altering the molecular composition of the assembly organofunctionalization and the incorporation of elemental "dopants".

摘要

多氧钒酸盐（POV）簇是多金属氧酸盐的一个重要子类，具有广泛的分子组成和物理化学性质。这些多核组装体一个相对未充分发展的应用涉及将它们用作块状金属氧化物的原子精确、均相分子模型。鉴于POV与扩展的氧化钒材料在结构和电子方面的相似性，以及修饰均相同类物相对容易，研究原始和修饰的簇配合物的化学和物理性质提供了一种方法，以了解结构修饰（晶体结构/相、表面配体的化学组成、元素掺杂剂）对扩展固体性质的影响。本综述总结了使用POV簇作为块状金属氧化物的原子精确模型的最新进展，特别关注氧化钒簇的组装以及改变组装体分子组成（有机官能化和元素“掺杂剂”的掺入）的后果。
