摘要
近年来,有机光致变色材料持续引起人们的研究兴趣,因为此类化合物在分子开关、防伪及生物荧光成像等领域都展现出了广泛的应用价值.螺吡喃(SP)类化合物具有制备方法简单、容易修饰和光学性能较好等优点,能在光、热、电、酸碱及外力等多种外部刺激下发生结构和性能的改变,因而可被应用于多个领域.无基质的固态螺吡喃类化合物因为分子堆积紧密,缺少空间自由体积,难以发生光致变色反应.开发固态下具有光致变色的螺吡喃是新材料领域的一个重要发展趋势.以分子结构与性质之间的关系为重点,全面总结了固态光致变色螺吡喃材料的研究进展.
Abstract
In recent years,organic photochromic materials have drawn continuous interest due to their wide application value in fields such as molecular switches,anti-counterfeiting and biological fluorescence imaging.Spiropyran(SP)compounds have the advantages of simple preparation,easy modification and good optical properties.They can undergo structural and performance changes under various external stimuli such as light,heat,electricity,acid-base,and external forces.Therefore,they can be applied in multiple fields.Solid spiropyran compounds without a matrix are difficult to undergo photochromic reactions due to their tightly packed molecules and lack of spatial free volume.Development of photochromic SP in the solid state is a significant trend in new materials.The research progress on photochromic spiropyrans in the solid state is summa-rized with the relationship between molecular structures and properties as an emphasis.
