title: 3,3,4,4,5,5-Hexafluoro-1-(2-methoxyphenyl)-2-[5-(4-methoxyphenyl)-2-methyl-3-thienyl]cyclopent-1-ene: a photochromic compound.
abstract: The photochromic title compound, C(24)H(18)F(6)O(2)S, has thienyl and aryl substituents on the C=C double bond of the shallow half-chair-shaped cyclopentene ring. The planes of the two substituent rings are inclined to that of the cyclopentene ring, with dihedral angles between the mean plane of the cyclopentene ring and those of the phenylene and thienyl rings of 51.2 (1) and 51.3 (1) degrees, respectively. The molecule adopts an antiparallel conformation, with a distance between the two photoreactive C atoms of 3.717 (2) A.
