用X射线晶体学方法研究了1，2-双（2，5-二甲基-3-噻吩基）全氟环戊烯的单晶光致变色性。用线性偏振的单色360 nm光照射晶体，并用X射线衍射仪分析。X射线晶体学分析表明，开环异构体转化为闭环异构体的转化率高达8%，反应以顺旋方式进行。噻吩环中的两个硫原子和活性碳原子明显改变了位置。通过用650 nm光照射，光生的闭环异构体完全返回到晶体中的初始开环异构体。
Single-crystalline photochromism of 1,2-bis(2,5-dimethyl-3-thienyl)perfluorocyclopentene was studied by X-ray crystallography. The crystal was irradiated with linearly polarized monochromatic 360 nm light and analyzed with an X-ray diffractometer. The X-Ray crystallographic analysis showed that the conversion from the open-ring to the closed-ring isomers was as much as 8% and that the reaction proceeded in a conrotatory mode. Two sulfur atoms and reactive carbon atoms in the thiophene rings clearly changed their positions. The photogenerated closed-ring isomers completely returned to the initial open-ring isomers in the crystal by irradiation with 650 nm light.
