1-(2,5-Dimethyl-3-thienyl)-3,3,4,4,5,5-hexafluoro-2-[5-(4-fluorophenyl)-2-methyl-3-thienyl]cyclopent-1-ene: a new photochromic diarylethene compound

Abstract: The title compound, C₂₂H₁₅F₇S₂, is a new unsymmetrical photochromic diarylethene derivative which can potentially be used for photoelectronic applications such as high-density optical recording and photoswitches. The distance between the two reactive C atoms is 3.572 (5) Å; the dihedral angles between the central cyclopentene ring and the thiophene rings are 44.7 (7) and 46.1 (7)°, and that between the benzene ring and the attached thiophene ring is 36.4 (8)°.
