摘要：

Photochromic reactivity of a dithienylethene dimer, 5-(2-(3,4-dimethyl-2-thienyl))-3,3,4,4,5,5-hexafluorocyclopent-1-enyl-2-(2-(2,4dimethyl-3-thienyl))-3,3,4,4,5,5-hexafluorocyclopent-1-enyl-3,4-dimethylthiophene, was studied in solution as well as in the crystalline phase. In solution two kinds of closed-ring form isomers were reversibly produced upon irradiation with ultraviolet light, while in the crystalline phase only one kind of closed-ring form isomer was produced. The different reactivity was attributed to the difference in the distance between two reactive centers in the crystal. (C) 2002 Elsevier Science B.V. All rights reserved.
