The title compound, C(29)H(23)F(6)NO(2)S, a member of a new family of photochromic diaryl-ethene compounds having an unsymmetrically substituted hexa-fluoro-cyclo-pentene unit, displays dihedral angles between the indole and thio-phene rings of 52.5 (4)°, and between the indole ring and the planar C-C=C-C unit of the cyclopentene ring of 53.8 (6)°. The distance between the potentially reactive C atoms from the two heteroaryl substituents of 3.817 (6) Å is proven to be short enough for photocycli ...[more]
