制备了由三种不同的二乙烯，1,2-二（2,5-二甲基-3-噻吩基）全氟环戊烯（1a）、1,2-二（2,5-二甲基-3-噻吩基）全氟环戊烯（2a）和1,2-二（2-甲基-5-对甲氧基苯基-3-噻吩基）全氟环戊烯（3a）组成的新型光致变色单晶。在适当波长的光照射下，三组分晶体变成黄色、橙色、红色、紫色、蓝色、绿色或黑色。晶体的颜色在黑暗中是热稳定的，在可见光照射下完全漂白。这种多色光致变色晶体具有应用于光电子器件的潜力，如多频三维光存储介质或全彩显示器。
Novel photochromic single crystals composed of three different kinds of diarylethenes, 1,2-bis(3,5-dimethyl-2-thienyl)perfluorocyclopentene (1a), 1,2-bis(2,5-dimethyl-3-thienyl)perfluorocyclopentene (2a), and 1,2-bis(2-methyl-5-p-methoxyphenyl-3-thienyl)perfluorocyclopentene (3a), have been prepared. The three-component crystals turned yellow, orange, red, purple, blue, green, or black upon irradiation with light of appropriate wavelengths. The colors of the crystals were thermally stable in the dark and completely bleached by irradiation with visible light. Such multicolored photochromic crystals have potential for the application to optoelectronic devices, such as multifrequency three-dimensional optical memory media or full-color displays.
