研究了三种二芳基乙烯衍生物在多孔氧化铝上的光致变色性能。在紫外光和可见光的交替照射下，具有噻吩环的二芳基乙烯容易分解，而具有苯并噻吩环的衍生物发生可逆的光致变色反应。二噻吩基乙烯类化合物的开环异构体开始分解。根据化合物的氧化电位探讨了其分解机理。
The photochromism of three diarylethene derivatives was examined on porous aluminum oxide. Upon alternate irradiation with UV and visible light, the diarylethenes having thiophene rings decomposed easily, while a derivative having benzothiophene rings underwent a reversible photochromic reaction. The decomposition started from the closed-ring isomers of the dithienylethenes. The decomposition mechanism was discussed based on the oxidation potentials of the compounds.
