聚氧乙烯酸盐（POMs）作为一类典型的离散金属氧化物簇合物，在无机化学和结构化学领域有着广泛的应用前景。然而，与化学合成相比，光化学，电化学和磁性，结构不对称性，以及由此产生的相关特性的研究远远落后，即使它们对于功能材料非常重要，特别是在溶液体系中。其主要原因之一是很难控制和保持多金属氧化合物的稳定手性态，从而难以进一步发挥相应的性能。为了克服这些缺点，本文主要讨论了离散金属氧化物团簇的手性产生，通过超分子方法进行手性转移，自组装中的手性放大，以及相关的功能特性，如光致变色，催化和生物活性。考虑到以前的一些评论涉及的手性结构和包装结构的多金属氧酸盐的结晶固体，本文只集中在诱导的手性和材料性能的溶液系统，这是最近比较活跃，但没有评论文章涉及这一有趣的领域。
Polyoxometalates (POMs), as a typical class of discrete metal oxide clusters that are known in inorganic and structural chemistry since long, have displayed more and more interesting applications over recent years. However, in comparison to the chemical synthesis, the photochemical, electrochemical, and magnetic properties, the structural asymmetry, and relative characteristic investigations arising therefrom are far behind even if they are very important for functional materials, especially in solution systems. One of the main reasons is that it is hard to control and maintain a stable chiral state of POMs to carry out further corresponding performances. Aiming to overcome these disadvantages, the main concerns of this review are to discuss the generation of the chirality for discrete metal oxide clusters, chirality transfer via a supramolecular approach, chirality amplification in self-assemblies, and the related functional properties such as photochromism, catalysis, and bioactivities in solutions. Considering that some previous reviews dealt with chiral structures and packing architectures in the crystalline solids of POMs, this article only concentrates on the induced chirality and material properties in solution systems, which have been more active recently but no review article has been involved in this interesting area.
