光致变色材料的制备、性能及变色机理

Preparation, properties and photochromic mechanism of photochromic materials

光致变色材料可广泛应用于光信息存储、民用生活、防伪、军事等不同领域,引起人们越来越多的关注。本文主要综述了有机类(含螺吡喃、螺噁嗪、偶氮苯、二芳基乙烯、俘精酸酐、席夫碱)、无机类(含多金属氧酸盐、过渡金属氧化物、金属卤化物)以及有机-无机复合类光致变色材料的制备、性能、变色机理和研究进展,同时,简单介绍了光致变色材料的应用,最后对其研究发展做出展望。

Photochromic materials have gotten intensive attention in various fields, such as optical information storage, civilian life, security, military and so on. In this review, the preparation,properties, photochromic mechanism and research progress of organic photochromic materials(including spiropyrans, spirooxazines, azobenzenes, diarylethenes, fulgides, Schiff base), inorganic photochromic materials(including polyoxometalates, transition metal oxides, metal halides)and organic-inorganic photochromic composites were summarized. Meanwhile, the applications of photochromic materials were briefly introduced. Finally, the research development was prosposed.
