提出了一种具有三甲基硅基的光致变色二乙烯的新功能。在紫外和可见光交替照射下，二乙烯在聚合物薄膜和溶液中表现出光可逆的光致变色。在100℃下加热后，有色状态立即变为无色，与开环异构体不同的是，无色状态在紫外线和可见光照射下都是稳定的。这种光致变色材料可能被用作秘密显示材料。
A new function of a photochromic diarylethene, having trimethylsilyl groups at the reactive positions, has been developed. Upon alternating ultraviolet and visible light irradiation, the diarylethene showed photoreversible photochromism in a polymer film, as well as in solution. The colored state changed to colorless immediately upon heating at 100 degrees C. The colorless state, which is different from the open-ring isomer, was stable under both ultraviolet and visible light irradiation. Such photochromic materials could potentially be used in applications as secret display materials.
