摘要
多金属氧簇-紫精基化合物是一类由紫精和多金属氧簇通过配位作用、阴阳离子的静电吸引以及氢键等相互作用构建的化合物.在此类化合物中多金属氧簇作为富电子的无机构筑块起到了提供电子的作用,将电子提供给紫精阳离子,从而赋予材料结构设计多变、良好的光热稳定性、多刺激响应等优点,实现了有机-无机杂化材料应用的升华.文中综述了近年来多金属氧簇-紫精基晶态化合物的合成、结构与性能、刺激响应中的电子转移途径,及其在智能传感、光催化领域的应用研究,最后总结了目前该领域发展的难点和不足,并提出未来的研究方向.
Polyoxometalate-viologen-based compounds are constructed by viologen derivatives and polyoxometalates via coordination bond,electrostatic attraction of anions and cations and weak hydrogen bond.The polymetallic oxygen clusters are introduced to the structure functioning as electron donors for its electron-rich inorganic nature,providing electrons to viologen cation.This strategy sublimates the application of organic-inorganic hybrid materials and serves an effective method.This kind of material features diverse structure designs,favorable photothermal stability and multi-stimulus responses.This review summarizes the synthesis,structure and properties,and the electron transfer pathway in stimulus response materials of polyoxometalate-viologen analogue crystalline compounds,together with their applications in the field of smart sensing and photocatalysis in recent years.At last,this review summarizes the challenges and shortcomings in this field and prospects for future research.
