title: 3,3,4,4,5,5-Hexafluoro-1,2-bis(5-hydroxymethyl-2-methyl-3-thienyl)cyclopent-1-ene.
abstract: The title compound, C(17)H(14)F(6)O(2)S(2), a photochromic diarylethene, is one of the most promising materials for optical memories and other optoelectronic devices. The hexafluorocyclopentene group and the two thiophene rings are all planar, and the dihedral angles between the cyclopentene ring and the adjacent thiophene rings are 46.4 (1) and 49.5 (1) degrees.
