The title compound, C(61)H(68)F(8)O(2)S(2), is a photochromic liquid crystal based on diaryl­ethene as photoswitchable unit. The F atoms connected to the benzene rings are disordered over two positions; the site-occupation factors refined to 0.830 (3)/0.170 (3). The mol­ecule adopts a photo-active a...

description The title compound, C(61)H(68)F(8)O(2)S(2), is a photochromic liquid crystal based on diaryl­ethene as photoswitchable unit. The F atoms connected to the benzene rings are disordered over two positions; the site-occupation factors refined to 0.830 (3)/0.170 (3). The mol­ecule adopts a photo-active anti­parallel conformation and the distance between the two reactive C atoms of the thio­phene rings is 3.448 (3) Å. The dihedral angles between the central cyclo­pentene ring and the adjacent thio­phene rings are 43.56 (3) and 48.58 (3)°. These structural elements exhibit a suitable geometry for photochromic behaviour in the crystalline state.
