A number of inorganic and organic materials exhibit redox states (reduced and/or oxidised forms) with distinct UV-Visible (electronic) absorption bands. When electrochemical switching of these redox states gives rise to different colours (i.e. new or different visible region bands), the material is described as being electrochromic. By virtue of their numerous applications, both of academic and commercial interest, electrochromic materials are currently attracting a great deal of interest. This review provides an introduction to the major classes of electrochromic materials, namely transition metal oxides, Prussian blue systems, viologens, conducting polymers, transition metal and lanthanide coordination complexes and metallopolymers, and metal phthalocyanines. Examples of some new materials and of prototype and commercial electrochromic devices are cited.
许多无机和有机材料呈现出具有不同紫外可见（电子）吸收带的氧化还原态（还原态和/或氧化态）。当这些氧化还原态的电化学切换产生不同颜色（即新的或不同的可见光区域吸收带）时，该材料被描述为电致变色材料。由于其在学术和商业方面的众多应用，电致变色材料目前正引起极大的关注。本综述介绍了电致变色材料的主要类别，即过渡金属氧化物、普鲁士蓝体系、紫精、导电聚合物、过渡金属和镧系配位络合物以及金属聚合物，还有金属酞菁。文中列举了一些新材料以及原型和商业电致变色器件的实例。
