中文摘要	The title compound, C25H14N4F6S2, is a new symmetric photochromic diarylethene which can potentially be applied in optoelectronic devices, such as optical memories, photo switches, and color displays. In the crystalline phase, this molecule, which has crystallographic twofold rotation symmetry, adopts an antiparallel conformation that can undergo effective photocyclization reactions by a conrotatory mechanism. The distance between the two reactive C atoms is 3.642 (7) angstrom. The dihedral angle between the central cyclopentene ring and each thiophene ring is 48.0 (2)degrees. The colourless crystals turn green when exposed to UV radiation and the process is reversible when exposed to visible light of appropriate wavelength.
