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 summarized with the relationship between molecular structures and properties as an emphasis.

Key words: spiropyran, solid state, photochromism
